I'm sure that's it; MultiSelect is only a Property of Listboxes...not Comboboxes. The only Comboboxes with this type of capability are those displaying a Checkbox for each selection, as you mentioned...which means that the Field is a MultiValue Field, and they demand all kinds of special handling, not seen in other Datatypes...which is why most experienced developers eschew their use.
