fn key causes crash, R50p

[guansoon]

Happy owner of an R50p recently experience "blue screen" crash when fn key is pressed after thinkpad has been running for a while. Have not identified exactly when it happens, but I remember that if I hold down fn & punch any key without an fn-designation (i.e. brightness up/down, light on/off, screen on/off), blue screen occurs & thinkpad reboots.

I'm getting worried. Anyone with similar "fn key causes crash" problem?

R50p: I run XP Pro, SP2. I have 512Mb RAM (yes, I should upgrade). I use a dock. I usually run Photoshop, MS Office, Handbrake, Mozilla, Camera-control software & Scanning software on machine.
