Video question for Dale/Jim

[Steve Bauer]

Guys, I had a slight glitch (I think) with the demo last night.......the laptop video window was playing and the show monitor was playing great. I believe previously that I could double click the computer video window to "full size" it or "click and drag, resize" it etc. Now I can't. It remains the small window in the upper left corner and resists any and all attempts to do any different. The show monitor works fine.

I have read the manual on video but it simply says, double click or click and drag, and neither works.

Any suggestions?
