ms access - get 65K records only listed in combo box from a table of 155K records

Question

I have a table of 155K records. I can scroll only 65K records in combo box of a form having recordsource with query or sql, selecting three fields from that table. Why it does not list all 155K records even the query, which I am using as recordsource, shows all records outside of the form.

Answer 1

perhaps the item index is a 16-bit integer

a better question would be, do you really expect the user to scroll through 155 thousand items in a combobox?
