(Even the MacOS sometimes gets confused.) But now LC is doing crazy things — even when no external monitors are connected. I’ll move the mouse to the top of a stack window, and ask for the Mouseloc and it will return something like "100,-60”. If I click a button in the middle of the stack, the click will register in an object the 60 pixels above that. It’s not always 60 — the wrongness changed as I move the stack around. Other times it works fine. I can’t find a pattern to set it off.

With multiple monitor, zero vertical is the top of the top most monitor

desktopChanged message may also be helpful as it is sent when the 
displays/monitors change
