-- Information about the crash:
- What I was doing when the application crashed:

I'd just pluging in a usb dongle for a wireless mouse and wanted to see if it had registered. I was running Firefox in ull screen mode, so hit F11 and then tried to hit the little arrow to show the rest of the System Tray applications and the bottome tool bar thing crashed.

-- Backtrace:
