Well, if the screens in the Window Layout regions panel are the right size and position, then this is probably specifically related to LOTRO + Win 7, so I will have to specifically test LOTRO on Win 7 in order to solve this problem. I imagine I might need to make a change to how IS is overriding LOTRO's stupid window centering crap. That has to be one of the dumbest features anyone ever put in a game.
