I compiled and ran your test program with current fltk2 svn (r8842)
on Windows 7. If you want to receive mouse RELEASE (and DRAG) events
you must make sure to return non-zero on the PUSH event (that's what
you were missing).

uncomment this, i.e. use:
return 1;
or set a variable, maybe
ret = 1; // int ret needs to be declared before

if you didn't return in your code above, then modify this to
return (fltk::Window::handle(event) | ret);

Note that you won't see the output under Windows when it happens,
since stdout is buffered if you run it with MinGW (or Cygwin), so
either use fflush(stdout) where appropriate, or use something like
setvbuf (stdout,NULL,_IONBF,0); // set stdout unbuffered
in your main program.
