I am using PB 2019 R3 2703 Trail.
I am trying to switch an MDI application to the RibbonBar. I start the application and select a window from the Ribbonbar, it is called but it is not visible. With the old menu everything works.
The call in the program code is done with "opensheet" or "opensheetwithparm". If the call is made with "open" the window is displayed.
