Are others using this feature successfully? I can use it, but if I go out to another program or try to turn it off, Vegas becomes unresponsive, and I have to use task manager to close it and start over. I have always been one to save while I'm working on a project, similar to voting in Chicago, early and often, so I haven't had to redo a lot of work because of this, still it is annoying. Otoh, being able to output the video preview to an old Amdek Color-I I have left over from my C64 is very nice.

I suspect it might some sort of issue with my display card. Nothing fancy, an ATI Allinwonder 7500 Radeon.
