I'm a bit of a newbie to firebird and have had a problem where every
time I access the server where my firebird service is running &
database is located my users get the following error message when
their Delphi 7 applications try to access the database:

The requested operation cannot be performed with a user-mapped section
open.

This has only happened since my colleague also accessed the server
last week. Can anyone tell me what is likely to be causing this
problem?

Cheers,
S
