I have managed to install virtualbox on my mba 11.6 with win 7 as the guest. I have a few problems and wondered if anyone can help me please. 1. The only way I can move from win 7 back to osx is to hold esc and drag the cursor down through the bottom of the win 7 window. Is this how its supposed to work? 2. I have set up a shared folder on osx and set it up on virtualbox but cannot mount it as instructed through the command menu. 3. Virtualbox doesn't recognise my pen drive but osx does. 4. Would it be advantageous to use win 7 lite as I only have 160 hd? Excuse my asking seemingly simple tasks but I'm struggling with it, and cannot put anything on win 7 until I master it. Thanks.
