How can I set up the Design Editor to display both dialog and Property Palette styles of dialogs?
If you set the default for properties to the Property Palette (using the toolbar button or Options menu item) and display the properties, you will see the palette window open. If you then switch to Property Dialogs (button or menu item), when you double-click an object in the Navigator, the dialog will appear, even though the palette window is still open. Once you dismiss the dialog, you can set any properties in the Property Palette that were not in the dialog. For example, you prefer the dialogs but can only set text properties like Description or Notes in the palette, so you use the dialog to do what is possible there and enter the text using the Property Palette.
