I recently ran a number anti malware programs and did a major Windows upgrade to my XP virtual machine. Now the icons in my MAC doc will no longer launch the apps...they bounce, open XP (if it isn't already running), show a little blue dot beneath the icon (to signifiy that the app is running) but nothing opens or runs in the Windows environment. The same thing happens if I select an app from the Windows XP Applications folder on the dock. Any suggestions?
