(I looked, but couldn't find a bug for this, so here goes.)
Launching any game (say, Braid Demo) hangs quickly.
To work around this, go to Settings > Friends > "Notifications and Sounds", uncheck all checkboxes, and select "Never" for "Flash Window".
Then go to Settings > In-Game and uncheck the "Enable Steam Community In-Game"
checkbox. The game should launch ok now.
