What is RowSourceType in both cases? Is SET FILTER involved?

Hi Sergey:
In some cases RowSourceType is set to 0(none). In other cases it's set to 4(query).
Ogher times the listbox is populated in its INIT.
SET FILTER is not involved.
Do you think it matters if you populate via a query in RowSource or not?

Hey, I lived in the Bronx for many years.
