X41 Tablet blue screen when touched with pen after undock

[fm13]

I have a X41 Tablet (1869-5CG) with preloaded XP SP2 and all updates (drivers, firmware, software).

This is how I get blue screen:

- X41 is connected to X4 dock
- press the power button on dock, wait for Windows to boot, log on via external keyboard
- press undock button on dock, wait a few seconds
- remove X41 from dock, open screen
- touch screen with pen -> BLUE SCREEN

Anyone experienced same problem?
Can someone with X4/X41 try this procdure?
