Hi, that is the problem with using buttons lik this..

you will need to use a movieClip instead.

example:

make a new movieClip
on frame 1-10 you have your background color change

on frame 1: you have a stop(); action & a delete action, like this:
Code:
stop();
delete this.onEnterFrame();
now make a new layer (call it actions layers)
put this code on it:
Code:
this.onRollOver = function() {
	direction = "play";
	this.onEnterFrame = function() { 
		if (direction == "play") { 
			this.gotoAndPlay (nextFrame());
		}else if (direction == "rewind") { 
			gotoAndStop (prevFrame());
		} 
	} 
}
this.onRollOut = function() {
	direction = "rewind";
}
