I'm running Vista, fully updated. I have two windows open in firefox, both with a dozen or so tabs. I was shifting them around, and accidentaly moved one about halfway off screen. Now it's stuck there, and whenever I try to move it back, it moves slightly, then freezes and won't let me do anything until I hit ctrl-alt-del; then when I hit cancel and get back to my desktop, the window has gone back to it's original offscreen position. I've tried closing everything, running C-Cleaner, and restarting my computer, but no luck. The window comes back in the same place and glitches the same when I try to move it. I can move the other Firefox window without problems, as well as Word and Digsby windows. Any ideas?
