I have installed Parallels on a new 24 inch imac. After about 2 hours parallels quits. I have tried different memory allocations to no avail. I uninstalled everything from the mac and started over and same thing. The only thing i use windows for is to play poker online. The only thing i have downloaded to windows are the system updates, ie7 and my poker client. I used the default settings and also made sure parallel tools were installed. Another very weird thing is my imac has crashed twice since installing parallels. The screen turns grey and a msg tells my shut down via the power button (or something like that). I have sent 4 e-mails to parallels tech support starting 6 days ago and have yet to hear back. Any suggestions. I do have the newest build 3188. thanks
