You don´t miss anything Cetin! I´d like to know a way to do this whithout any changes in my forms incluing the scx! When you create a new form, you create a new instance of the basic form, right? I´d like to do the same with the datasession, create a new datasession based on the default datasession. Create datasession as defaultdatasession. Something like that! Now, i can do what you sugest. I´ll open my scx and alter the BaseClass of my forms.

Thanks a lot!
