Works okay on my machine here at work. But when you exit, it left my windows res at 640x480 instead of dumping me back to 1024x768 ... Had to manually go into the screen properties and change it back.

Mouse movement seemed a little laggy, as if the timer for the update on the image wasn't fast enough.

Edit: I just noticed a little window sitting on my desktop. It reads:

Access violation at address 0046B985 in module 'gvtest2.exe'.
Read of address 00000040.

Machine specs:

Compaq 1.7Ghz 256MB, Win2000Pro, NVidia Vanta 16MB (Latest drivers)

....

I'll try my two machines I have at home later tonight...
