Hi, Just as the title suggests, when running Parallels 4 in Coherence mode, with a Windows Vista guest, there is always a portion of the Vista desktop visible on screen, and it is possible to interact with the desktop - right-click, drag/click any visible icons etc. The screenshot below shows what I see: Other (OS X) windows can sit on top of the visible Vista desktop and obscure it, which is fine - however, the Vista desktop obscures part of the Mac desktop, which is rather less desirable. This is a recent problem - I've not seen this before, though have had other minor and short-lived glitches in the past. This seems rather more persistent than any other. Any thoughts? Many thanks
