Trying to use a VM in full screen mode under osx 10.9 (mavericks) is completely borked in parallels 9. If you enable osx full screen mode and disable use all monitors in full screen mode you end up with a fullscreen mode that looks like the non osx fullscreen mode in that it uses the current space. It does hot however disable the menu bar and it somethimes overlays the vm screen making it hard to click on objects close to the top in the vm. If you enable use all monitors in full screen then it behaves almost correctly. However the extra monitor is not used but the VM sees it and uses it even though its not visible. I have downloaded a evaluation version of fusion 6 and it seems to have none of these problems. Please fix this as it makes multiple monitors unusable even though its advertised as one of the major new items in the product info. -Ivar
I'm having the exact same issue. Very frustrating, especially since it all worked well under Mountain Lion and PD9.
