Hi! I have a Ubuntu Linux (10.04) installed on Parallels 7 (newest update, at least installed newest two days ago). I run Ubuntu on MBP 2010 late mode in OSX Lion using Lion's Fullscreen feature. The problem is that I want that it would be "impossible" to go away from fullscreened Ubuntu to the Mac OSX accidentally. I mean, there is a menu bar in top of screen of Ubuntu (and I want to keep it there). When I move my mouse up to that menu -> Mac OSX Lion menubar will pop ups over that Ubuntus menu and as you can guess, it is very annoying. So I have tried "Smart mouse" Off but then the graphics bugs so much that it is not a solution. When it is off I can keep my mouse cursor inside Ubuntu what I want, but when it is on or auto -> OSX menubar will be visible and I don't want to see it. TL;DR; version: How I can force my mouse stay in Ubuntu until I press Ctrl + Alt without Smart Mouse Off because it bugs?
