I just upgraded to Parallels 5. I downloaded and ran the installer, which seemed to go fine. But when I try to launch Parallels 5, after the icon bounces for a couple of minutes, nothing happens. It sits on my dock, but there's no dot to indicate it's running. However, according to the Activity Monitor, it is running. I restarted my MacBook Pro (15" Late 2008 unibody, 2.8 Ghz., 4 GB RAM) and ran the installer again but there's no change. I'm hoping someone from Parallels will see this and help. I was running the beta to version 5 before this and version 4 before that, all the way back to version 2.
