I am having a repeating, not not constant, problem with screens getting "stuck". I need to click outside of parallels to have my image updated. This is especially true when browsing on web. Started with install of beta 3. Ocurrs on Mac Mini, 1.83 ghz, 2 gb memory, lots of free harddisk using XP pro and DVI monitor. only thing I can think of is that I have a lot of applications open simultaneously Very clearly a problem of "focus". If Parallels windo has focus, screen gets stuck (and cursor may spin). As soon as finder get focus, Parallels screen updates and proceeds normally. I can see screen updates occuring while Finder still has focus. As soon as I click back to Parallels window, screen freezes again.
