Kevin,

Hmmm ... my bad I guess ... I didn't look before I typed. <g> All I remember is thinking how weird it was that the SelectedIndexChanged fired a gazillion times before the form even comes up. I think I switched to using the SelectedValueChanged event instead (which I think is quirky too, but not as bad) ... I've even, in some cases, had to resort to just using the Validated event (which I don't like to do unless I'm really stuck because it forces the user to have to tab out of the combo ... but, oh well).
