(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.

I learned a lot (“desktopChanged", "the working screenrects,” difference between "the screenrect" and "the screenrects," etc.) I have a hunch, though, my problem may relate to stack RevMenubar and some accommodation the IDE makes for “the mouseV” depending on whether RevMenubar is showing or whether you have your own menubar or whether that screen has a menubar in it  —  I dunno. I’ve never understood how this works. I notice sometimes, though, when I turn on Toolbar Text, it shows up about 100 or 200 pixels down.

You might also look in the dictionary at the windowBoundingRect property 
- I think it only controls that are that windows van be maximized to, 
but I forget the details. It is yet another screen area related 
property. I am also not sure that windowBoundingRect is multipel monitor 
aware as there is no "windowBoundingRects" (plural) version.
