I am using Parallels Desktop for Mac with Windows 7 as the guest operating system. I am trying to run WordPerfect Office X6 (most recent version) and it runs fine unless I turn on MacLook. When I do this, WordPerfect crashes and will not load again. When I turn off MacLook, I can run WordPerfect again with no problem. Does anyone have any idea what may be causing this and how I can fix it?
