In general, drawing other objects while inside anotehr object's
FL_DRAW handler is kind of iffy in double mode. Prior
to issuing FL_DRAW, the backbufer is switched on. Now if
while handling this FL_DRAW, you issue commands to draw
other objects, either via fl_redraw_object() or by
fl_set_xxx that results in a redraw of another object,
another FL_DRAW for that object will be issued that
can potentially screw up the window/clipping setting
of the first FL_DRAW. In your case, I don't quite understand
why it is MotionEvent that causes trouble. I will look into
it.
