2 screen question

I put Parallels on a MBP about 2 months ago & at that time could run Mac on the laptop & Parallels Windows on a second monitor, but now when I open parallels it only opens on the Mac side & I cant move it to the second monitor - any help please? tx Neville

 

What mode? Coherence, Full Screen, OS Window, all of the above?

I could not get Coherence'd window apps to cross the Apple menu bar when I had an external LCD over my MBP LCD. If I moved the Apple menu to the top screen I was fine, as was OS Window and Full screen with no regard to the bar.

I ended up moving side by side to avoid the issue entirely, but kind of preferred the over/under.
