listbox: how to remove selection by external click??

[grayhalo]

Hello; I've got two list boxes set up in a movie and need to make it such that when I click on an item in one, it removes the rollover or selection highlight in the other. This is probably simple but I can't find any information on it... Can someone point me in the right direction? Thanks.

Try using mylistbox.selectedIndex = undefined;
