【问题描述】：
我是 Tkinter 的新手和新手，对我来说很轻松。我试图正确编码，但我一定做错了什么。这些都是我面临的问题。
问题：
- 只要我移动滑块，Python 就会崩溃，尽管程序继续运行？？随机
- 虽然缩放按钮与滑块的代码相同，但它不更新图形？
- 人偶周围有一块大黑板，看起来很垃圾
- 代码的一般速度很差。
崩溃（继续运行）是：
- 运行时错误！程序：C:\Python27\pythonw.exe [MS Visual C++ 运行时库]
- 异常未知软件异常 (0x40000015) 发生在应用程序的位置 0x1e06016a [TclNotifier: pythonw.exe]
这些是我真正想知道的，只是为了完善程序，使其反应灵敏且友好。
感谢您的帮助
