Thanks for posting that. A quick glance shows the 945G machine is very

I would be surprised if 64 or 32 bit made a difference. Basically your results
have ruled out that it's related to whether a 64 bit OS is used. Screen
resolution difference also seem unlikely (I've reproduced the problem at
640x480 on my EeePC). I would be surprised if it is RAM related.
