Buttons don't work after adding onPress

Question

I have an MC that has a graphic. I have faked buttons for just the over state, so it shows a border around a portion of the graphic. That works fine until I added this to the MC:
this.onPress = function(){
    if (this._currentframe != 1) {
        rewind = true;
The onPress function does what it should do, but the buttons no longer show their over state when I hover over them.
Any ideas?

That's true. Only problem is there not equal quarters, so some might be circle, and others weird shaped. I guess I could make a button that covers the entire thing with no hover. And then put the border buttons on top of that. And hook the rewind control to all the buttons, so all the area is covered.
This is what i originally used for the whole thing:
_root.adinstance.onPress = function(){
    if (_root.adinstance._currentframe != 1) {
        _root.adinstance.onEnterFrame = function(){
             if(_root.adinstance._currentframe != 1){
                   _root.adinstance.prevFrame();
             } else {
                   delete _root.adinstance.onEnterFrame;
However, if I try:
_root.adinstance.btn1.onPress = function(){
    if (_root.adinstance._currentframe != 1) {
        _root.adinstance.onEnterFrame = function(){
             if(_root.adinstance._currentframe != 1){
                   _root.adinstance.prevFrame();
             } else {
                   delete _root.adinstance.onEnterFrame;
It doesn't work. I tried adding a trace after the onPress of the button and I didn't get anything.
Do i have some syntax wrong???
