Forms need to be added to the _Screen.Forms collection, involve a dual instantiation process with the Load/Init event pair, and might cause data environments to be loaded, as well. Scrollable forms require more resources, as do forms with a private datasession. I think the Form would be the worst choice if you need a non-form class.
Thank you for confirming that form is a bad choice. I didn't know about all the things you mentioned above (like GDI resource, collection, etc, etc.). I will stay with custom class then.
