What I’m trying to do is code a basic OpenGL 2.0 window, when I run the code from a file, it works for the first couple of runs, then it dumps errors. If I run the same exact code from the IDLE GUI, I get a window every time. The following is first a list of added Python 2.6.6 packages, the code and the errors. Am I using any conflicting packages? Am I missing a package? My imports work in the IDLE GUI. Any help would be great!!

Sorry for the length of the post, I just wanted to fully document the problem. The Py install is running on Win XP SP3, IDLE header:

    I tried this and it worked in my case,

    1. went to http://pypi.python.org/pypi/PyOpenGL-accelerate and downloaded the zip source package.
    2. using 7zip I extracted the package to a folder named PyOpenGL-accelerate-3.0.1
    3. then using a command prompt, navigated to the folder I just created

    4. I typed C:\python26\python setup.py install to execute the package install

      Once this completed, I ran a basic OpenGL script in IDLE, Dr.Python, and PythonWin. All three IDEs were able to create the correct OpenGL window (a 400×400 window, black background, and a white wire-frame teapot.) without any errors. With this solution I was able to keep Numpy 1.6.
