Everything appears in the designer, even with the visible property set to .F., and nothing appears at runtime. Have you tried this with the base classes, adding things code and changing properties to match your form with the problem, until the problem reappears?
The weird thing that happens is that if I'm in the form designer & set the Listbox Visible property to .T. and then .F., the listbox remains visible during the current form designer session. When I reload the form into the designer the next time, the Listbox goes back to being invisible. FYI, there is also another container class in the container (class) control besides the command button.
