Odd - there was a vaguely related post recently about problems with
enter/leave on fltk-2, and I had done a little test to see how it
behaved (fltk-2 seems to be suspect, fltk-1.1.x and 1.3.x seemed fine.)
Anyway, the thread is... here:
http://www.fltk.org/newsgroups.php?gfltk.general+v:26622
I just ran my test again, with a few printf's added to report the
enter/leave events and they seem to be consistently matched - I don't
seem to be seeing any extra leave events.
How does my simple demo work for you? Maybe the problem is platform
specific (I've got OSX and Vista here just now, seem to be fine.)
