Having the same problem
This is very frustrating (you probably could've guessed that). I've tried all the direct, obvious, and esoteric solutions I've seen out there:
Reinstall Parallels tools - fail
Ensure Advanced>Copy & Paste>Share Mac clipboard is checked - fail
Ensure Secruity>Integration>Isolate Mac from Windows is unchecked - fail
Ensure Shared Profile is checked - fail
Try setting Time to "Sync from either OS" - fail (though several said this worked for them)
Boil a chicken's shadow at midnight - fail
Severely limits the usefulness of this tool. Seems to be a recurring problem from version to version for some subset of users.
Is there any answer from Parallels on why this happens and how to reverse the problem?!?
Need help!
Thanks
Running Parallels Build 8.0.18608 (Revision 898384; July 17, 2013) on OS X 10.8.4 with a Win-7 VM fully patched and updated.
