fltk-1.3.x-r6916
I have a window with only one active item, a button (not counting
three active, but empty groups). When the mouse leaves the entire
window, I get a FL_LEAVE event over and over again, i.e. each time the
mouse leaves the entire window. It doesn't hurt anything, but it
doesn't seem correct either since the mouse never FL_ENTERed the
button to begin with.
Here's a fluid file to demonstrate the behavior.
