mouse messages to invisible controls

invisible buttons are not the solution, since they are invisible for the 
mouse, too :-(

But :-D :

Create your buttons, script them, place them and then, TADA, in the 
color-palette
set the ink of them to "noop".

This makes these buttons (and everything else) invisible only for
our eyes and not for the mouse ;-)

I have been doing things like this for a long time, works wonderful...


Hope this helps...
