As It's possible to see in the movie, moving the windows does not follow the mouse and even when is not clicking, continues moving ..

We have investigated but couldn't immediately pinpoint where the issue lies. I suggest to inherit from TForm instead of TTMSFNCRibbonForm, and just use the ribbon as a control.
