Good morning,

Let me show you how i have it in the previous version of the Application without the ribbonbar.

This window is as a  presentation/initial window, all the sheets you open are open over this presentation window.

When i migrated to pb2022 R3, this initial sheet appears as a tag of my TabbedView called presentación,

I don't like this because the idea of this sheet Presentación is to be by default behind al the tags in the TabbView, not like a tag that we're going to select.

The idea is that if I close all my sheets, this will be the one that appears by default and must not be shown in the tabbview.

Regards,
