Design in Flash - Easy custom cursor

Hi, It's an easy one.... I need help. I want to have a customs cursor inside my FLA. But, since I added the customs cursor. I'm no longer able to click on my hit zone. Why ? In order to understand. I duplicate the SAME file: one with a customs cursor and the other one without the customs cursor. Please help me and tell me why i'm not able to click and activate the GotoAndPlay with my customs cursor. I'm sure it's easy. Everything is on AS3. Thanks, P.
