Video output stops when going to another app?

[meeble]

Hi,

I wish I could figure out how to fix this problem. We use Live for our live shows, and have video being played back in Live being sent to video projectors. (the video window is set to full screen, btw) But, when I switch to another app, the video window disappears and the desktop is displayed instead on the projector. Is there any way to tell ableton to keep displaying the video window even though another app is selected? The audio doesn't stop when Live isn't the foremost app, why should the video stop?
