Every time I access WinXP pro through boot camp and then switch back to accessing it through parallels I get the "Warning Parallels tools is installing..." message. This happens every time I switch back and forth. It wouldn't be so bad if parallels tools then worked correctly but many times mouse sync is turned off and the checkbox is grayed out. The enable coherence mode is also grayed out. I then have to uninstall and reinstall the tools for everything to work correctly. Is this a known issue? If not, I just wanted to alert the developers to this. Cheers. - Using a MacBook Pro 2.0ghz core duo.
