Running OS 10.6.4 on a unibody MacBPro 13" with Parallel 5 / Window Home 7. Every time I restart or start up, Parallel starts loading windows. I have checked OS 10.6.4 in the Preferences start up disc to no avail. When I shut down Parallel, it states "Windows is running, do you want to shut down ? What do I do to start up in the Mac enviroment again?
