It's not clear how you refresh the second listbox. It would be helpfull if you post your code.

>I have a listbox (#1) from which I select a month. Based on the month I do a query into a cursor which I then populate into another listbox (#2).
>Two things puzzle me.
>1) Many times when I click on the first listbox #1 (whichs kicks off the query), the last item is not displayed in listbox #2 unless I click on the vertical scroll bars. This doesn't happen all the time, but often on the first time through.
>2) Then, sometimes when I choose a different item from listbox #1, the 2nd listbox goes dark and I get nothing back. Then again, if I click on the vertical scroll bars, everything is ok.
