The mouseDown message may not reach the data grid group in all cases. For
example, I know it is not passed during column resizing operations. You
should add the mouseDown message to the "default header behavior" if you
want to process it. This lesson shows how to customize the header behavior
in order to add tooltips. Just follow the instructions but add your
mouseDown handler rather than the tooltip code.
