Help! Simple, but I can't figure it out

How do I do a onRollOver detect without using the onRollOver function?

I have a movieclip and when it’s rolled over I have it zooming using the AS2 tween function.

In that movieclip there’s a form with fields, and if I use the onRollOver function on the movieclip to zoom, the whole movieclip becomes a button thus preventing any input into the form fields. Is there an alternative I can use?

I tried using hitTest, but it keeps looping itself unlike the onRollOver function that only runs once.
