Happy Thanksgiving!
This is a minor annoyance, but it's happened to me 3 times in 2 days so I figured I'd letcha know.
I'm using Chrome 7.0.517.44 and when I've gotten a PM, the screen goes "dark" (as usual) but no dialog pops up and the browser gets stuck (I have to hit back to get a working page again).
It could be just me, but I wanted to see if anyone else had this problem.
