I was creating bitmaps to use as container icons for my custom classes. When I look at the default bitmaps for existing classes you'll notice that the background is transparent both in the project manager and in the clas browser? When I create my bitmaps, I can always see the backgrounds in the project manager, but not in the class browser. Does anyone know if there are any special settings I need to make when saving a bmp so that it will display properly as a container icon?
