I originally set up Parallels to launch my Mac browser when accessing web links in Win XP. Now I want to undo that and have Firefox on XP launch web sites instead. No matter what I do, I can't stop Parallels from launching my Mac browser. I have turned off PC to Mac sharing and also Mac to PC sharing and restarted the virtual machine, I have edited my prefs in the applications menu (but they don't always stick.) How can I stop Parallels from launching my Mac browser?
