I have both XP and Vista running on Parallels 3.0 without any problems. After installing each I have 2 aliases on the desktop, one for each OS. The problem is I can't get either alias to appear in the dock when they are not running. I would like to drag & drop (or something) to get the 2 icons to appear in the dock, so I can click on them and have the guest OS launch. I can put other aliases on the dock, and I've tried creating new aliases for each guest OS and they behave the same way.
