In standard PowerBuilder applications, you can prevent duplicate toolbars from displaying in MDI applications by setting the Application object’s ToolbarFrameTitle property to its ToolbarSheetTitle property. However, if you deploy the same applications in .NET Windows Forms projects, the duplicate toolbars still display when you open a response window or a sheet window from a frame window menu.
Also, if you open multiple sheets in these Windows Forms applications, it is possible that duplicated toolbars will display. [CR 535917]
