Alternative way to move windows around screen
MercuryMover
Although it's a paid-for utility (which comes with it's own PrefPane etc), this is a great tool for chucking around your windows. You can also set it up to force windows to certain sizes on a shortcut, which is handy if you want to check out your web pages in a browser at 800x600, etc.
By default, you jut press CtrlCommandup-arrow and you get a little black pop-up window that helps you to move/resize the window that had focus when you pressed the shortcut. (the screen grab includes the PrefPane too).
