Getting System.ArgumentOutofRangeException when hitting ESC on new row on bound datagridview

Need some help troubleshooting this exception I keep getting.  I've bound a CollectionBase IBindingList class to the datagridview.  If I click on a new row, then click on the new row again to edit values, and then hit escape I get this error message.  Don't even know how I'd catch this exception.  Anyone got clues on this one?  Thanks.

System.ArgumentOutOfRangeException was unhandled
