I have a Combobox on a Form using a table as its RowSource and a different table for its ControlSource. It has been working fine. Now, when the form is opened it is diabled and becomes enabled if you go to the NEXT record. The drop down list comes up on a record about 90% toward the bottom. If you sellect a record toward the top, instead of staying on that record after selection, it returns to the same record 90% down. The RowSource table is used by several other programs. What makes the ComboBox act like this?

In advance, thanks.
