Navigation system with masks

Hello,
I used some actionscript from Kirupa under ‘scriptable mask’.

Does anyone know how to make the frame move freely according tothe movement of the mouse instead of just horizontally.
Do you know how I would be also be able to click on objects through this navigation?

It would be really nice if you can give me a hand since I honestly don’t know anything about actionscripts or masks.

Thanks so much
Carra
