Add a TIB_SessionProps to your datamodule (or whereever the
TIB_Connection is).

There are two properties that are interesting for you:
AllowDefaultConnection (I have it false)
AllowDefaultTransaction (I have it true)

I had this problem a long time ago and I could just handle it by using
the SessionProps component.

By the way:
I had a lot of problems with my D5 using ProjectGroups (ie having two
projects opened at the same time - since my main datamodule has the same
name (dm) in every project Delphi started to mess up everything. I don't
use project groups anymore (okay, I have to use them, since I can't
switch them off, but I don't add more than one project to it....)

Maybe BCB has a similar problem.
