> Not without seeing the statement that is requested when the

exception occurs. What does the IB_Monitor show?

The error message only occurs in a PC I won't access before 10 days.

I didn't think to use IB_Monitor as the query is surely correct (it
works on a local database and on a LAN database).

As it does not work when used in a slow internet connection (and not
always), I assume that the problem could lie in the data transmission
speed.

For instance, I think I read that you cannot issue a query (in the
same transaction ?) if the remote database is still sending data of
the previous query, or something like that.

Next thing I will do is assign the 2nd query to a different
transaction.

I will experiment and report the results.

Thank you
