I created an Excel file and used Active X to create some drop downs to
select several different functions related to graphing. It works fine on
a couple of PC's but on the 3rd all I get is an outline of the drop down
with a red X. I uninstalled/reinstalled Office 2003 and all of the
Office updates, but that didn't help. Does anyone have any thoughts on
how I can resolve this problem?

Thanks.
