在Python 2.6.6中使用pyopengl遇到问题

Question

我想做的是编写一个基本的 OpenGL 2.0 窗口。当我从文件运行代码时，前几次运行是正常的，但之后就出现错误。如果我在 IDLE 图形界面中运行完全相同的代码，每次都能成功打开窗口。下面是我添加的 Python 2.6.6 包的列表，还有代码和错误信息。我是不是用了一些冲突的包？或者缺少了什么包？在 IDLE 图形界面中的导入都能正常工作。任何帮助都非常感谢！！

抱歉帖子有点长，我只是想详细记录这个问题。我的 Python 安装在 Windows XP SP3 上，IDLE 的头部信息如下：

Python 2.6.6 (r266:84297, Aug 24 2010, 18:46:32) [MSC v.1500 32 bit (Intel)] on win32
