I bought the retail pkg of Parallels last September and it seemed to work fine, However, with each successive upgrade, the program gets flakier and flakier. Messages like the "OS is already in use", etc, etc. It's always something with this app. Now, using the latest build, the program starts to load OK, but as soon as it attempts to go 'full screen' the image becomes garbled like bad TV reception. I've reloaded the program several times. It occasionally works, then returns to its wayward ways. In my opinion, the program is so unstable that it is useless. Never had these problems with Virtual PC...., but, of course, it was V-E-R-Y slow. I'm ready to ditch Parallels and give VM Ware a shot.
