How come I can't resize my Vista window, i.e., if I make the Mac window larger the interior Vista window stays the same size with just more black border around it??
I did have Parallel Tools installed. I read another forum which suggested unchecking the "Change Mac OS X resolution" box in the center of the appearance tab for Preferences (Parallel).
I checked and already had it unchecked. So I took a chance and checked it. That worked for me I now have a full size XP Window.
