Thanks! This is a step in the right direction, but I still have a problem. I can now get the projection on the wallwhile the computer monitor stays the same. But the only way that would work was if I shifted the toolbar in the Displays prefs to the monitor. When I do that, and go to full screen on Modul8, I lose the cursor on my Mac. It just disappears. When I command-T my way back to non-Full Screen mode in Modul8, the cursor reappears.
Help! And thanks!
