Commenting-out the Click event code allows the DblClick to fire. Changing the _DoubleClick system variable seems to make no difference.

Thanks BL,

The fact that Click & DblClick aren't intended to be used together on the same control is what I needed to know so I could quit bashing my head against the brick wall.

There are plenty of other brick walls available for me, so I don't need to waste my time on this one!!
