mouse glitch periodically

[zflaky]

Hi, there. I faced with mouse glitching problem in some specific situations.

 

I found when you are running programs, like Office Word, which have an area has a keyboard cursor blinking, then your mouse will glitch. The temporary solution is moving your mouse out of that area. But it is very inconvenient for lots of text processing applications.

 

Do you have any ideas to fix it?

 

My mac version is 10.6.3 and my display card is GMA950 0x27a2.

 

Thanks a lot!
