Mario,

> I *have* set AllowDefaultTransaction to false.

Was this a typo? AllowDefaultConnection is the property relating to
this issue. Is that true or false in your application? It should
default to false.

There was a problem where the AllowDefaultConnection property was not
being checked - pretty sure it is fixed in 3.6Di. It is possible that
your forms/modules were saved while that bug existed and the
connection properties need resetting.

Can you please check the problem and make sure it does still exist.
That is, regardless of what is displayed in the IB_Connection
property - change something (eg. move a nonvisual component) to be
sure Delphi does resave the form/module and then try it out.
