I just tried your suggestion. No luck. I've also tried:
this.map.events.register('mousedown', this, function()
{ alert('foo'); } );
But this doesn't do it either. I'm now considering just adding an
event listener to the Map's outermost div, and managing the mousedown
event myself. Does anyone happen to know how to get a reference to
the right HTML element?
Thanks!
