(Even the MacOS sometimes gets confused.) But now LC is doing crazy things  even when no external monitors are connected. Ill 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. Its not always 60  the wrongness changed as I move the stack around. Other times it works fine. I cant find a pattern to set it off.

With multiple monitor, zero vertical is the top of the top most monitor 
- regardless of whether it is the primary monitor or not. The on 
desktopChanged message may also be helpful as it is sent when the 
displays/monitors change
