Hi again,
Alas, the problem is not solved
Sorry to hear that
I had the opportunity today to check QU on a dual set-up. It was with a laptop and projector running Windows 7.
After connecting to the projector I used the the Display item in Control Panel to set the extended desktop (it was the default).
I tried both the Page editor and Image Editor; after opening each one in turn, I dragged the editor window across to the projector screen. I could close and open those screens and each time they opened correctly where I had left them.
I suspect your problem is some conflict with the Mac display settings and the W7 settings. Did you make
all the settings through W7?
It's certainly not a QU problem.
Terry
