balloon help flickers, why ??

[lafourca@imag.fr (mathieu Lafourcade)]

I've implemented a key-handler that allows to switch on and off ballons (as
I find annoying to go back and forth to the menu, 'kind of bit lazy :-)

The called function is something like :

(defun switch-balloons ()
        (set-help (not (help-on?)))
 )

No problem, it works but... not so fine as when I activate by keys and I
would to switch it off by menu, nothing happens. After messing up a while
between key activation/deactivation and menu activation/deactivation the
balloon begins to really flickers before actually displaying the
help-string.

Is it a known bug or should I do something special ?
