Is it giving the right right row number for the second line, or
returning '2' rather than '1'?

I'm slowly getting an IBO development system together with the latest
source code, but I've a rush on other work just started as well :( -
Typical as I've been quiet since Xmas. I suspect that the MouseDown
event is right, but because we now have grid rows rather than headings
on row 0, any filter on the DblClick event needs modifying in these
conditions. I hope to be able to actually LOOK by next week ;)
