Symptoms

Customer may find that for a specific SGD user, when login from any Linux client and then launched a Windows application, the arrow keys, together with
insert/delete/home/end/pgup/pgdown do not work as expected and sometimes do alternative actions ("down" sometimes acts as if "Start" has been pressed, "up" may produce a small black box around the text caret, left/right do nothing etc.)

The issue may happen suddenly and the customer is not aware of any changes.

If using the arrows and similar insert/delete keys from the numpad (WITHOUT numlock engaged) they work.
The issue ONLY happens when launching Windows applications.
The issue ONLY happens when launching from Linux clients.
The issue does NOT happen when using the same Linux client/same SGD account by login with HTML5 client.
The issue does NOT happen when using the same Linux client/same application by login with other sgd accounts, it only happens with a specific
sgd account.

Below actions have been performed but no help:

1. Removed the .tarantella dir from homedir on affected clients, installed the client, tried multiple clients including fresh VMs and the behavior persists only with this specific account.

2. When the issue happens, launch a gnome-terminal at the same time and run below command:
# xprop -root | grep XKB
The output is _XKB_RULES_NAMES(STRING) = "evdev", "pc105", "gb", "", "", which looks good

3. The customer has restarted the Windows application server.
