The only way to clear this behavior is to reset the 'Do not prompt me again' switch
- Go to Tools | Options | Environment | Confirmations
- Click the 'Reinstate all confirmation messages...' button *
- The next time an error occurs, the user should only check the 'Do not prompt me again' box and close the Database Error window
* Note that step 2 will reinstate, throughout Toad, all the messages you have previously set to ignore.
