Clickable region of a movieclip

programming flash
1

Hi there :slight_smile:
had a problem
1] mask worked but masked as a the whole .png and not as the shape within the .png
fixed with
[AS]
btn1.cacheAsBitmap = true;
mask1.cacheAsBitmap = true;
btn1.mask = mask1;
[/AS]
2] I want to make the mask clickable and not the .png as the part that is masked is still clickable :?/

how do I sort that plz

thanks in advance
