Datagrid Error in Standalone

[Peter Haworth]

Getting this error in a standalone, doesn't happen in the IDE:

Type: Handler: error in statement
Object: group 'TaskList' of group 'DB_Activities' of card  
'DB_Activities' of stack 'Tasks' of stack '/Applications/BandTrak/ 
BandTrak.app/Contents/MacOS/BandTrak'
Line:
Line Num: 0
Hint: _table.DeleteDataControls

After the error is reported, the data in the datagrid is corrupted.
