I am running Parallels Desktop v4 under Snow Leopard and running Windows XP. The application is using 20% of my CPU when idle and upwards of 50% when I run a single application (Website Watcher) I don't have iTunes installed under Windows and the Monitor under Windows is not showing any excessive CPU usage under Windows. Does anyone have any idea what is causing this issue? The app makes my Mac unusable when it is running and when I use any application in Parallels I may as well not bother trying to use any other apps on my Mac. I'd like to be able to find a solution for this. Is it just related to v4? I don't recall having these issues under v3. Is it possible to downgrade? I actually only use Parallels for a single Windows app. While generating the problem ID Parallels was taking 70-90% of my CPU Report ID is 5842049
