I'd like to develop for JDE 4.5.
When a user clicks a button in my application, the app makes an HTTP connection and this may take a moment. I'd like to show a GIF file that I've already created, however, I don't want to completely push a new screen to the display stack but just a small popup image. I know this can be done with the class PopupScreen for JDE 4.6 and later, but I'm wondering how it can be done on JDE 4.5?
