I have had constant problems with the system freezing up at differing points with the VM and Mac. There isn't a particular point when it happens but it does everytime I use them. I have uninstalled and reinstalled Parallels on my MacBook Pro but it does nothing about this problem. I have even tried the last two builds for sure it is still freezing. I am running Windows XP Home Service Pack 2, 1 GB of memory, the latest Mac OS just for some additional information. If anyone has any help, I would gladly appreciate it.
