OK, I have a really simple example (attached) - just a box sitting
inside a window with a margin all around. I override the handle event
to report ENTER and LEAVE events but ... I see no ENTER events (!) and
a LEAVE event whenever the pointer leaves the box *or* the window(!!).
What is going on?
I'm running on Linux 2.6.21.5 . I'm seeing the same behaviour with
1.1.7 and SVN-r5857 .
The context is that I have a box widget that I want to respond to the
keyboard when the mouse is over it, so I want to call focus() on an
ENTER event. But I can't get the event!
TIA,
Jeremy Henty

Fl_Window *window = new Fl_Window(300,300,"Enter/Leave");
window->begin();
new Box(50,50,200,200);
window->end();
window->show(argc,argv);
return Fl::run();
