I just installed Hardy, and most everything's fine -- except for one thing. Pidgins entry in the window list doesn't blink/throb anymore when a new message comes in. I'm not sure it this is a pidgin thing or a gnome thing -- I'd test it if I knew of any other apps that use this functionality, but I don't.

Here's a picture in case I'm not being clear enough:

That button used to change colors and blink whenever a new message came in. Now it doesn't.

Any ideas?
