Hi I'm at the end of my tether with Parallels (5.0.9310) . I have a brand new 27" iMac, 30.6Ghz with 8GB RAM. It all runs fine until I start Parallels. Then anything to do with a finder action is unbearably slow. If I open a file or do a 'save as' in a running app, it takes ten seconds for the dialogue box to appear. If I close Parallels the problem persists until I reboot and leave Parallels well alone. I've tried dedicating 4GM RAM to Parallels but it still happens. Nothing in Activity Monitor suggests any excess CPU or memory use. Please help!
