Helen,

Thanks for the prompt response.
If you can address my responses below that would be great.

Well who would have thought of that<s>?

I set TIB_Connection.PasswordStorage to psNone and had no idea
iboDatabase was overriding it. I am not using a TIBODatabase. BUT I am
using IBODatasets (so I can use generic DB aware components, not
just IBObjects own flavors). Is that the same thing?

How do I FORCE it back to psNone?

I am not; but clearing the IB_Connection password property on
disconnect is working OK.

Thanks for the advice.
