I'd like to know when the user double-clicks on the gripper part of a toolbar. I can use the toolbar's doubleclick event but this only passes e as System.EventArgs, which doesn't contain the location where the user double-clicked. If he double-clicks on a disabled button then this event triggers as well, so the two actions seem to be indistinguishable. Any ideas how to just capture a double-click just on the gripper part of the toolbar?
