I used some Yahoo developer code that pops up a hidden menu when you click on a button (http://developer.yahoo.com/yui/examp...xample01.html). It looks like the js toggles between visibility:hidden and visibility:visible on the menu's parent div for the effect. Problem is that when we populated the menu with a list of items, the menu is really long. So I set the height of the containing div, set the overflow to auto, and it works great on FF, IE6, IE7 and Opera for PCs and Safari for Macs (the menu pops up and has a scrollbar). But on FF for the Mac the scrollbars show up even though the div is hidden. I think I understand why Mac FF is interpreting it this way, but I still need a way around this. Anyone with ideas?

and here is the code -
