Thanks, Tom, for a very quick reply. Just to clarify, the Dropdown
List (whose tool icon is the same as the Combo Box's icon) was greyed
out even before any controls were placed on the form. Hovering the
mouse over it displayed only "Dropdown List"
Experimenting, I went to Tools->Customize->Toolbox and then was able to
move the controls (Dropdown & Combo) around on the design toolbar.
Dropdown List was suddenly not greyed out while in Form design.
Still, if I now try to put a Dropdown List control on a form, Access
repeatedly throws an error ("The constant you entered for control type
is invalid"), eventually crashing. I have read that the Dropdown List
is only supposed to be used on Data Access pages, so dropping it on a
Form is an error. Is that correct?
So I may have solved my problem myself since the Combo Box and DropDown
List are now available for Data Access pages, and (somewhat) for forms
as well.
