strange behaviour with display, please help

[arthur]

i have TP42p KTU-2373 and noticed strange behavior with my display,
- 14" ATI 128 FIREGL. after 2-3 hours work it seems the content of any window where a mouse is over is disappeared. i upgraded to the latest driver set from ibm (ati actually) the same things.
anyone have something like that?
thanks

Actually the drivers from ATI and IBM are not quite the same. Should use the ones from IBM exclusively unless you are a gamer.
