Well, I'll
never do ANY kind of programming/scripting after a full day of school and work, before going to bed. I've been busy with this all night long
But that's had positive consequences too. I've thought of the following theory: upon a call to _TrackMouseEvent, <some message>* will be posted to the window when the mouse moves over it. When the mouse leaves the window, some other message is posted.
* Can this be WM_MOUSEMOVE?
