[MX2004] Horizontal Sliding Menu depending on mouse position

I have a masked horizontal menu that slides from left to right when I roll over 2 ‘hit’ MCs (left position/right position). That works fine but I have buttons under the ‘hit’ MCs that won’t work since my ‘hit’ MCs are on an upper layer. I thought about working with MOUSE POSITION MOVEMENT but I’m not sure how to do this.

Any suggestions on how to work around this problem?

Thanks!
