Ok thanks.
I'm now using the database restored for Firebird using FIBPlus as
connection front end. I have used IBExpert to backup/restore the file.

By the way, i have been unable to restore the database for Interbase. I
have tried Iterbase 5, 7.5 and 9 without any success - always same error
: unsupported on-disk structure!

Since i'm now with Firebird, do i still need the Interbase drivers
(dll) and server?
