No problem...if I figure out i'll certainly post the answer here.

I'm sure it's not a ram issue...more likely it's a radeon thing if this other guy has one too...or maybe a combo of radeon/amd boards...

I was reallly hoping that wouldn't be the case, but from what you say it's a fairly plausible explenation. Is he using a Via chipset? which model radeon?

I never had this problem in 4.5...

I'm hopeing it's a coincidence.
