This is not a big glitch. When running the demo in full screen mode, the control/escape keyboard shortcut did not bring the program back to the controls, only the "file, edit, etc. heading at the top was visible. Now, that said, i must admit that I am running the demo on an OLD G-4 450 sawtooth mac with AGP graphics, only 16 mb VRAM. This hang could be due to the insufficient hardware. I will run the demo on my iBook G-4 1 G machine with 32 mb VRAM. Also, I will run dual monitors from that machine, so, again, this is probably NOT a big problem, probably hardware related.
