who has neither ownerships nor group access rights . That said, I
couldn't reproduce the error with gsec, although I could with ISQL.

It won't solve this problem, but it will forestall others. I'd also
recommend that you match the client libraries to the server if
possible. That can be another source of problems, as no-one does QA
of mismatched server/client combos.

Thanks for the info, I'll get the binaries later on today and test.
Our main site uses Citrix and I have discovered that if I login as
anyone on Citrix other than the Administrator the problem does not
happen. Very odd, as you would have thought that the Administrator
would have all access rights.
Is anyone else aware of issues with Interbase / Firebird with Citrix?
We are about to be heavily dependant on this combination and I'd
prefer to know the pitfalls sooner than later.
Thanks again for the advice.
