Yes, I'm aware of popup but I suspect it's not gonna do what I want. I'm trying to create an "appbar" - a Microsoft type toolbar that pops up when you drag the mouse to the edge of the screen, except that the MS one doesn't work reliably or do everything I want so I'm making my own.
I need a one-pixel wide window that I will make one or two inches long that sits "on-top" at any chosen edge and detects mouse movement, at which point it pops up a toolbar window (which could be itself, expanding in size) and goes away automatically a short time after the mouse has left the popup window.
I don't think popup will work for the narrow on-top, mouse movement detecting window part of this because popup grabs the focus as soon as it appears and dies as soon as it loses the focus - right ??
What I want is more like a floating on-top toolbar with no title-bar.
What do you mean when you say "it can get called" - do you mean I will have problems trying to bypass SyncCaption?

Hm, what about just periodically detecting mouse position?
