I've been using Parallels for some time now and it's an invaluable part of my work regime. But there is one thing that drives me crazy and crashes my machine. I _never_ want to click on a document file that is on my Mac and for parallels to then open to try to run the Windows app that shows that document. And I mean never. I run XP and Vista and Linux under Parallels but I keep getting documents (e.g. .swf) that then get registered to Windows under the Mac. I can't keep going through and fixing every association and even when there is no Mac association I don't want Windows to open. Why? Because I have Parallels open already and it then opens another version of Vista, locks up and my Mac crashes meaning I have lost all work in both my Mac apps and my Windows apps. Is there any way to tell Parallels to never associate icons from the Mac to Windows. Here's hoping there some way of switching this off globally. Thanks all.
