Thanks for the input folks, however I keep tweaking the settings, and I'm still randomly getting this problem.

The only solution is to log out of the client and start it back up again. Yesterday I had a similar problem happen but in reverse, instead of the cursor bouncing off the window, as it had done earlier in the day, the client wouldn't "let go" of the cursor. When I tried to move to my main window, the curser kept getting held back ?( I'm at a loss to figure this one out. I can't seem to peg it to any certain key strokes or events.
