The addon in question is gonna be bartender 4, I can already say. It appears that the loot window positioning is directly based on where my bars are located.

Ex. My hunter has a pet bar but my Priest does not this appears to be moving the default position of the loot window.

I am thinking I will have to download MoveAnything when I get home and try positioning the windows in the exact position on the screen.

What is the default key for mouse repeater?
