Closing the table makes the grid lose its RecordSource, which accounts for this behaviour.

One approach would be to create a cursor to power the grid. You could then ZAP it and repopulate it with impunity.

Otherwise, be sure to set your grid's .RecordSource to "" and your columns' .ControlSources to "" before closing the table. You can then re-establish them programmatically when you re-open the table.
