Here's the minimal bit. Note that it works fine with busy cursor simply
because of the fl_deactivate_all_forms() in prohibitInput - we never see
enter/leave events. This is still a hack, but it's xforms/ only, so
super.
(of course this means we must deal with unbalanced enter/leaves, I
think)
Still compiling, so ...
