I switched from VMWare back to Parallels with v4 because it seemed fast and was easy on the Mac's processor. For the first week or so that was true, but now it's really not. When I resume a suspended XP VM, it doesn't take long - maybe 45 seconds. Then the VM is completely unresponsive for several minutes, while the Mac is bogged down. Then for several more minutes, various apps are drawn in a partial state and the VM is almost completely unresponsive. Then it's just slow for a long time. If, after this maybe 10-minute process completes, I haven't given up, I have a relatively fast VM to work with. Any idea what's going on? I tried rebuilding the VM from scratch but no luck. Thanks.
