I know you installed and reinstalled Parallels Tools, but just out of curiosity...
In the Device Manager under Windows, is the mouse driver the Parallels driver and the version of the driver corresponds to build of Parallels you're using (does it have the number 5600 at the end, if that's what you're using)?
Another suggestion, have you played with the ' experimental ' Direct shaders settings to correct the Media Viewer problem?
Another thing, none of these problem happen if you run in Full Screen mode in your internal display?
