@Sebastian : True, but as stated Lee, the problem is that the active zone is set to the object, not the animation. wich limits the uses you can make with the button. (basicaly it can't lead to a too big button or it will make for a very large area of blank space).
Of course we can imagine a whole system where the animation and the zone are not in the same button, making the button cease to exist as soon as we over it etc ...
@Lee : Indeed, I already make use of that new interface class trick (I saw it on another post, probably written by you ;p).
But since I use a verbcoin I hoped to put it all in a same interface so it would not bug out when the verbcoin is open on the far reach of the screen.
But I guess I could cheat by creating a background image with the button and a transparent background of roughly the same size of the VerbCoin though ...
Much tinkering to do !
Thank you both for your input !
