I am using SQL7 I have a connection and I relate two tables. The controlsource of the grid uses the table. One of the fields in the grid is called listbox. Sparadically, when the users the user adds data to this grid object an error occurs that .mnConn is not valid, this is after I have a connection.

The problem is .mnConn is a property of the form and the grid column is bound to the cursor. Why would I get this error and the column has nothing to do with the property.
