I have a from with 5 different LookupCombos. All of them are working
fine except one.

When the user opens the form and clicks any of the combos, the drop-
down list of the first 4 LookupCombos appears using the space it
needs to show all of it's columns.

When the user clicks the 5th one, the drop-down list shows only part
of the column titles and the horizontal and vertical scrollbars. The
user can still navigate to the value he wants with the scroll bars
and select it. If he clicks again, now the list appears complete and
without scroll bars, just as the other four lists do.

The properties of all 5 LookupCombos are the same, they go through a
"PrepareCombo" procedure to make sure of that. The only difference is
that the erratic combo shows 4 columns and the other four shows just
2 columns.

Any help would be appreciated.
