Hi Ursula, Georges,
Otto has already answered the solution. You must click twice at the same
point. This may not be the same as a double click if you move the mouse
between the two clicks.
This algorithm was implemented at a time where TCanvas::HandleInput was
not supporting double clicks. I will modify the algorithm to accept
also the more natural behaviour with a double click.
