I just updated to Parallels 3.0 for Mac Build 5626 and can no longer access Mac applications from the Guest OS (Vista). I have reinstalled the update. I have run Install Parallels Tools. I have all the settings set to share applications. I have uninstalled Parallel Tools in the Guest OS several times and reinstalled using both 'Complete' and 'Custom' installs. I have run 'Populate' multiple times. I am not running any anti-virus apps in the Guest OS. ... all to no avail -- no Mac apps are available in the Guest OS. Suggestions / help would be most welcome. Thanks! Trevor
