我在visualAge中新建了一个applet的小应用程序，在可视化组合界面中选择了几个button，并编译成功。但是我重新打开visualAge后，我所建立的界面看不到了，运行时没有问题，可以看到我所建的button，在历史记录中看到我总是打开我所编写类的影子类。如何解决谢谢！

The field of application development is so full of fine products, picking five personal favorites proved to be a real chore. Even settling on a pet IDE (integrated development environment) was hard.
