Combo displays null but has data

[John]

I have a list sub form with a combo box in MS Access 2000.

For some reason the combo box displays null but when I
tab or click on the control the data appears but only on
the combo box that has the focus.

Any combo box I put the cursor on the data appears.

If I close the form and open it again the combo box is
null again but will come back when the combo box has
focus.

I have copied all of the objects into a new database and
still have the same problem.

Any suggestions?

Please post the RowSource, ControlSource, BoundColumn and ColumnWidths
properties of the combo. It sounds like the first non-zero width
column of the combo (the one which will show when the combo isn't
dropped down) isn't correct.
