Salut Rolf,

did you extract the balloon class out of gb.form and changed it, or copy
the whole gb.form and made the balloon changes there ?

If you cloned the balloon class, what I see as the better way, it's
wiser to rename it, because you guess right! Gambas (at least gambas2)
can't overloading.
