Yep, twice last night. Other problem I'm having is my computer keeps locking up while playing. Screen freezes, mouse and keyboard are completly locked up. Have to power down and power back up to fix it. Compaq told me it was a low system resource problem, but I shut off everything running in the background, and generally have 90+ % system resources free before firing up AcesHigh. I've got a reasonably hot machine (550 MHz w/128MB of RAM), so I don't buy Compaq's excuse. I think it's the Compaq-built S3Savage4 video card, myself. Sorry to digress, but it's frustrating. Happens while playing other 3D programs, too.
