Hello, José Antonio,
Thank you for reporting this undesired behavior.
Currently, the possible solution that I can suggest is to activate the main form after calling the RadOverlayManager.Close:
RadOverlayManager.Close()
Me.TabInicio.ElementTree.Control.FindForm().Activate()
I hope this information helps. If you need any further assistance please don't hesitate to contact me.
Regards,
