One thing I would check is to make sure the BoundTo property is .T.

>But every now and then when the user fires the form, the picklist face is empty (ie. like row zero). When the picklist is then chosen by the user, all the rows are there (so the combo was built properly it seems). Also, if I have the user call me, I can check their users.dbf record across the network at that moment and the bound field does indeed still hold the correct data.
