Just stumbled across this, and I'm surprised that it hasn't been noticed it before. Well, it's a rare occurrence that the fix is needed...
Resetting the window position doesn't reset the Playlist or EQ (or other none main windows)
This needs to be addressed as I just managed to lose my playlist off the edge of a screen somewhere and the only way I could get it back was to add a massive 'moveable' layer to the PSD like 1000px wide to drag it back in.
