My monitor is set at 1400x900. I normally run WoW in full screen. When its windowed, I'm guessing it goes down to 1200x900 with the "PIP" being set at 400x300.

I'll try setting WoW1 to my screen size and the other a bit larger, thanks for the MSpaint tip! Be nice if I could get the PIP off the action bars, just incase I need 'em.
