Caps/Caps Lock problem with Wyse X50L via WLAN

Hello!

I’m about to set up some X50L devices connected via WLAN to our Citrix XenApp 4.5 farm. Almost everything works with one exception: The Caps/Caps Lock keys behave weird. At first, the Shift key doesn’t work, but if I release it, all letters are typed in capital letters (as if Shift Lock has been pressed instead), if I press Shift Lock, the typed letters are in lowercase again. To get back upper-case letters, I have to press Shift twice (!) – really strange.

This behaviour does only occur unter the following circumstances:

* It’s an ICA session. In Control Center, an xterm windows, a local Firefox or even a RDP session, the keys work as they should.

* No Ethernet cable is connected to the device at boot time (i.e. the first connection is done via WLAN). If an Ethernet cable is connected at boot time, the keys work fine, even if I pull it afterwards and the ICA session will be reconnected via WLAN.

So it looks like an ICA problem, but why does it only occur with WLAN connections? Are there any ICA parameters that should be changed?

The versions:

SUSE Linux Enterprise: 11.0.112
SLETC: 1.4.1115
OS Version: 2.6.27.42-0.1-pae
ICA client module: ica-11.100-01.09

Thank you!
