Hi John.

But when I click on the combobox, the display value goes blank,

This is a known issue. Change the RowSource to something other than 2-Alias or 6-Fields and this problem will go away.

the currently dipslay value is not selected and when I select an item, it displays until I move form the row, then reverts back to the original value.


Hmmm. This sounds like you are doing something like issuing a Refresh() in the interactiveChange of the control.

Just a shot in the dark here: Do you have the combo's BoundTo property set to true? You have to do this when it is bound to a numeric value. Actually, I set BoundTo to true in my base class combo because, even when it is bound to character data, setting BoundTo to true does not hurt anything. It really should have been the default < s >.
