The Array based combobox sometimes shows the correct list in the listbox, but sometimes it shows the correct list for a split second and then the list disappears and a solid gray color covers up the listbox.

What is rowsource for listbox? What it has to do with SET FILTER? Can you use a SQL for ListBox RowSource?
