Ahh, of course, I should've noticed the _MouseMove in Spinner.bas. _MouseMove doesn't really work well on MacOS. There's a GLUT issue that's pretty tough to resolve according to the devs. Right now the command causes a .25 second delay every time it's called. That would explain nothing moving onscreen since it's in the loop. If I disable that line and run the program _FullScreen (so the pointer stays fully onscreen), it works just fine.
The program does have a nice arcade feel to it!
