case sensitive search, collation drivers problem

hello!

First, I'm new with Interbase.

My main problem is the case sensitive search. So I have
tryed the collation drivers from Brookstone. It didn't work, I get
the message "subtype 21 not implemented".

And I have another problem, that could be related to the first
problem: I create a database with character set ISO8859_1 and dialect
3 (using IbAccess), but I can't connect to the database. The error
message that I get is "character set ISO8859_1 is not installed"

thank you in advance

George
