Wasn't sure what else to call it. The window with my DF taskbar houses... a LOT of IM windows. I've noticed in this version that I usually have to click a couple extra times to make the highlighting go away upon receiving a new message. 3.0.5 fixed the issue with them not highlighting at all, but now they're STAYING highlighted!
Is anyone else seeing this?

This occurs with both Office Communicator, which we use internally at our office, and with Pidgin IM client. It seems to occur with ANY taskbar box that notifies, whether it's an IM or just an IE window or whatever else. Since my original post I've realized that if I click on the box, the highlight disappears after a couple seconds, rather than a couple clicks. It's like lag.
