flash actionscript: in the on(release) handler for your button, direct its timeline to its "over"
frame, direct the previous button to its "up" frame and define the previous
button to be "this" one:

on(release){
this.gotoAndStop("over");
prevBtn.gotoAndStop("up");
prevBtn=this;
}

numbered rollover buttons in a row, where on(release), that button stays
in the over position. Then if you click the next number in a row, the
hover state turns off on the previous and locks on the new one. Sorry if
this is confusing. Thanks in advance!
