Jim,
Twice already this night, the message stayed on my screen after I send it. Clicking on the "add new topic" or "reply now" button resulted in a double entry. Something wrong or is this a user-related problem ?

I can vouch for janvdc, I have had to remove the extra entries...I wonder if this was because we were both writing on the message at the same time. I noticed that janvdc had answered my post while I was writing another answer...

Aha ! Thanks for that remark, Brian. Only now I notice there's a feature that allows to delete one's own writings. I'll give that a shot.
