That answers the question perfectly, THANX GEORGE!!!

>DropDown fires before the list drops. When fires after the selection is made and the list returns to the up position. It also fires when the user presses the down or arrow keys. In this latter case, DropDown doesn't fire. In both cases, When fires before the change (if any) becomes visible to the user. The actual value has changed, but When fires before it can be seen.
