2. Miscellaneous
================
2.1 Changing Server List
------------------------
If you find that the list of available servers in the Server field of
the Properties dialog appears to change, this is because you have access
to more than one network with a number of servers on each. Normally the
list reflects the network that the ICA Client is on, however depending
on network load and the load on the Citrix servers sometimes the other
network browser responds first and another list is displayed.

To produce a consistent list you should specify one of the servers on
the required list as the server browser in the Network/Properties
dialog.

2.2 Zooming in Adobe Photoshop
------------------------------
It should be noted that the Adobe Photoshop zoom out utility using
shift-leftmouse is not supported by the ICA Client for Unix. To use
this feature you should select the appropriate menu option instead of
using the mouse.

2.3 Resolving Names for Internet Servers
----------------------------------------
To allow you to resolve names of Internet Servers that you wish to
connect to, it is recommended that you have DNS (Domain Name System)
installed on your machine.

2.4 Attributes cannot be set for files on floppies
--------------------------------------------------
Attempting to set file attributes (e.g. using the DOS ATTRIB command or
Windows File Manager) on a locally mounted floppy drive silently fails.
The file attributes are left unchanged.

2.5 Problems moving files on DOS floppies mounted on Sun machines
-----------------------------------------------------------------
On DOS floppies mounted on Sun machines the client has to move files to
subdirectories by making a copy and deleting the original. This means
that it will fail if there is insufficient space for a second copy. The
Unix mv(1) suffers from the same limitation.

2.6 Problem copying large files to DOS floppies on SunOS
--------------------------------------------------------
On SunOS (Solaris 1.x) copying large files to a DOS floppy may fail with
a Disk Full error even when there is sufficient space.

This is because the WinFrame or MetaFrame server issues a FileChangeSize
request before writing the data, and SunOS cannot respond rapidly enough
to this request.

An entry IgnoreFileChangeSize with the value True may be set in the
[WFClient] section of wfclient.ini. This stops the timeout occuring
allowing large files to be copied. However this solution may have other
side-effects, and it should only be used if this problem is encountered.

2.7 Client Licensing and Multi-Homed Hosts
------------------------------------------
Client licensing relies on being able to determine a unique host id. On
Digital Unix and HP-UX the host id is obtained from the address of a
running network controller.

On multi-homed hosts the default is to use the first running network
controller provided it is up. This may be overidden by setting the
IdentificationController parameter in the [WFClient] section of
wfclient.ini to the name of a network device to use. For example "ln0",
"tra1", "lan2", etc.

2.8 Solaris (Intel Platform Edition) TrueColor support
------------------------------------------------------
The Solaris (Intel Platform Edition) client won't run on a 16 or 24-bit
TrueColor console as it relies on being able to select an 8-bit
PseudoColor visual, which Solaris (Intel Platform Edition) does not
provide in these modes.

2.9 Solaris (Intel Platform Edition) Second Mouse Button
--------------------------------------------------------
If you are running the UNIX ICA Client on a non-Solaris Intel machine
and displaying it on a Solaris Intel machine with a 2 button mouse, the
second mouse button will not work correctly.

To solve this problem add the flag "MapMouseButton2=true" to the
[WFClient] section of the file wfclient.ini.

2.10 Using UK Keyboards with WinFrame
-------------------------------------
International keyboard support for WinFrame servers is available by
applying the appropriate Unicode hotfix. However, if this hotfix cannot
be applied to your WinFrame server, UK keyboards can be supported as
follows:

i. Edit the file $ICAROOT/keyboard/keyboard.ini

ii. For Sun, HP, DEC and Silicon Graphics keyboards, uncomment the UK
keyboards in the appropriate section ([Sun], [HP], [DEC], or [SGI]) by
removing the semi-colon (;) from the start of each line.

iii. For Data General, rename the [DG] section to [DGkbd], rename the
[DG with UK] section to [DG] and in the [DGkbd] section enter a
semi-colon (;) at the start of the line "ButtonLabel = Data General" and
remove the semi-colon (;) from the start of the line "ButtonLabel =
US/International".

2.11 Error 49: cannot connect to server
---------------------------------------
This occured sporadically in 2.0 and 2.6 clients. A workaround was to
set 'InterfaceAddress=.' in the [WFClient] section of wfclient.ini This
now believed to have been permanently fixed in the 2.7 and above client
releases.

2.12 Correct operation of Client Drive Mapping with filenames containing 
     accented characters
------------------------------------------------------------------------
Correct operation of Client Drive Mapping with filenames containing
accented characters (e.g. ) may only be obtained by setting the Citrix
Server DOS codepage to 1252.

This may be accomplished by setting the server registry entry
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nls\CodePage\OEMCP
to 1252. However within a console window you may then need to set the
codepage back to 850 using the CHCP command in order for DOS
applications to display correct characters and accept alt-numeric
entries from the keypad.'

2.13 NumLock Operation On Linux
-------------------------------
The NumLock key operates incorrectly on some installations of linux. To
configure linux so that NumLock works, edit the file XF86Config (usually
located under /etc or /etc/X11). In the "keyboard" section make sure
that the following lines are either not present or are commented-out (as
shown below):

#    ServerNumLock
#    XkbDisable

2.14 Rapid Color Changes with TrueColor Displays
------------------------------------------------
When connecting to a Citrix server users are given the option of using
16 or 256 colors. The 256 color option assumes video hardware with
palette support which allows applications to rapidly change the palette
colors producing animated displays.

On a TrueColor display many colors can be displayed but there is no
facilty to emulate this ability to produce animations by rapidly
changing the palette. Emulating it in software is relatively expensive
in time and in network traffic. In order to reduce the the Unix client
is configured to buffer up rapid palette changes and only update the
real palette every few seconds.

Two new entries in the [WFClient] section of the wfclient.ini file
control the operation:

PaletteChangeTimeout=1
	This determines how long to leave between palette changes. The
default is 1 second. Granularity is in seconds. Setting to 0 results
in no delay between palette changes (at the expense of network traffic
and time delays). If a palette change arrives more than
PaletteChangeTimeout seconds after a previous one it is acted upon
immediately.

RedrawAfterPaletteChange=Yes
	This determines whether the screen should be redrawn after each
palette change. Redrawing should mean the screen reflects what the
application is trying to display but can cause a flickering effect if
the applications is trying to use palette animation. This is the
default value. A value of 'No' means the screen will not be redrawn
after palette changes. This means the new palette colors only take
effect when new drawing occurs.

2.15 SCO Unixware 2.1.3 - Unable to display in 16 colour mode
-------------------------------------------------------------
In some cases, the client session is unable to display graphics and text
properly. To compensate for these cases, the following line should be
added to the [WFClient] section of wfclient.ini:

ForcePlaneMask = True

2.16 SCO Unixware and OpenServer 5 - No audible warning check button
--------------------------------------------------------------------
The preferences dialog under menu entry Option, Settings... does not
display the check button to allow enabling/disabling of Windows alert
sounds. To disable audible warnings, make sure the following line is in
the [WFClient] section of wfclient.ini:

DisableSound = True

To enable audible warnings, use the following line :

DisableSound = False

2.17 Removing scrollbars from full screen sessions
--------------------------------------------------
Full screen sessions may be started without scrollbars by setting the
parameter NoWindowManager in the [WFClient] section of wfclient.ini to
True. The default value for this parameter is False indicating that
scrollbars will always be present in full screen sessions.

2.18 Color Approximation Limitations
------------------------------------
Color Approximation will fall back to using a private colormap if other
applications have allocated all 256 colors.
