Ok 2 things that are showing up immediately. First, iChat can't connect. crashes right after startup. But as soon as I turn Parallels off it works fine. Second, my windows partition disappears when Parallels loads (that part is fine), but it isn't coming back when it unloads ... no idea, I know it behaved this way in earlier versions.
ya know what, just ignore everything I've said today with the exception of the Beer/Pizza bit for the Devs. It was doing what I have listed above through like 4 restarts, and now I can't reproduce either issue.
