I've been having some problems using PopUpLists.  I have two lists of 4  
items each (the first item in each list can be thought as the default  
value).  I want to have button that will reset my lists to their default  
values.  For example, if the last item of a list were selected, when I  
pressed this button, the default value would be selected and would be the  
title of the list.  I thought that this would be a simple problem to solve  
but I can't find an easy way to do it.

Any help would be greatly appreciated.  Thanks.

When it's not actually popped up, a PopUpList stores its "current selection"
in the title of the button that does the popping-up. When theuser presses
that button, the button causes the popuplist to pop up; the popuplist 
queries the button's title, and searches for this title in its array of 
cells to determine which one to highlight. (If it's not there, it adds 
it --- see the popuplist docs.) To change the current selection, you can 
just use setTitle: on the button.

I'd be willing to help, but I need more information. Your address on the  
original posting is bad, and I don't want to waste bandwidth on the Net.  
Please contact me directly with a good email address.
