I am running Win XP on Parallels (got some old, but indispensable programs which need XP). After I open Parallels and then a folder or a file, the Win screen flips back to the Mac screen without me doing anything. Sometimes it flips back by itself after the file has been opened, mostly it does not, and I have to switch back to WIN manually. This is no lethal bug, but rather annoying. Does anyone have an idea? Thanks in advance, Klaus
