Button problem - wontn work with animation

I’ve got a button problem. I’ve created an iframe set and need the pages to load within the iframe - which should be simple, however, the buttons rollover state brings on an animation and if i set the button command, it either fires off the window everytime you rollover, or the click works but the animation doesnt.

Again, this is a problem i seem to have in flash 8. i’ve done this a few times before in flash MX and never had this problem. If anyone can take a look at my FLA and improve on it, i would be mostly grateful, otherwise it’s CSS links instead. i’m really running out of time!

thanks
