I've just installed build 3150 onto my macbook pro. I have a Windows XP VM which I created in build 3120 and a Windows Vista Ultimate VM which I also created in build 3120. If I start the Vista VM and try to open any application, or even control panel - the XP VM starts to load in the background - So I end up with both VMs running at once. This happened before and after installing the new parallel tools in Vista. Anyone else seeing this before I fire off a bug report?
