Your original post says that you did not RowSource. If you have a rowsourcetype, the combobox will not behave properly if you didn't specify RowSource.

You can do it this way in Load event if you don't want to do it visually:

With Thisform.ComboBox1
    .RowSourceType = 3
    .RowSource = "Select blah..blah.. "
    .ComboBox1.Requery()
Endwith
