Thanks GA! The flip command I "think" I have a grasp for, and your excellent info helps clear that up, thank you very much. ;)

But...in the graphics() command there is a parameter for "hz" which according to the docs:

"The hertz parameter selects a refresh rate, which refers to the number of times the screen refreshes per second. The refresh rates available depend on the graphics modes available, which differ from graphics card to graphics card. Note that creating graphics with an unsupported refresh rate will not fail - instead, a default refresh rate will be used."

I always just pass it a "0" because I thought this would cause the hardware to use a default value, but I think this is causing Blitzmax to try to default to 60hz. I'm hoping there is a way that doesn't mess with the user's refresh rate. I've read where alot of users don't like games to mess with their refresh rate.
