Listbox Always Selects First Value

[David Barger]

I have a listbox on a multi-tab form. When I select an item from the
listbox, it will always reset to the first item.

I have checked everywhere the listbox is referenced, and nothing fires right
after I select an item. (I put a msgbox with a reference message after any
mention of the listbox.) The only .Refresh or .Requery's appear where they
are needed and don't fire after I select an item either. (More msgbox's.)

I know this is very simple, but it is so very frustrating.

So, what would cause a listbox to requery or refresh immediately after an
item is selected?

Thanks,
