I am jealously reading other users talking about how Parallels 1922 is working well for them. I admit it is incredibly impressive to install XP, Office, Firefox etc and see it all run in a window on my Mac Pro. But all is not well. I can launch my 1Gb VM with Windows XP, but within 5-10 minutes it invariably locks up my whole machine (not just the Parallels process & window.) What actually happens is that the mouse continues to move, but no events appear to be processed. Once this occurs I cannot Force Quit, switch windows or perform any other activities on the machine at all. The last time it happened I noticed that iTunes (running on Mac OS) continued to play through to the end of the song, and I saw the mouse cursor change occasionally from the arrow to the watch or the spinning rainbow, but no events were processed. Eventually, after about 10 minutes, the mouse cursor even stopped responding and I had power down the Mac and restart. It's really frustrating because it is SOOO close. Windows is there, and it works (for a while.) I really don't know how Parallels is able to crash the whole Mac this hard and not leave any messages to explain what went wrong. If there is a way to enable more debugging output or locate a log for hints, then I will be glad to provide more info. I have converted the expanding disk to a plain disk, tried with VT-x both enabled and disabled, limited Parallels total ram to 1.5Gb, and other steps. So far nothing has alleviated this dreadful problem. If you can help, please let me know. I'm online on IM almost all the time: rickrossjl on AIM/Yahoo/Skype, email@example.com on Jabber.
