There were bugs in the graphing machinery (C:\Python20\visual\graph.py)
released a few days ago for Python 2.0 on Windows. You can get a fixed
version at
http://cil.andrew.cmu.edu/projects/visual
The download machinery has been revised. You can either re-download the
complete VPython package and unzip it into C:\Python20, or you can simply
download just the Visual component that contains graph.py.
This is how we'll handle updates in the future. The complete VPython
package that you add to Python 2.0 will always contain the latest versions
of everything, but you will also be able to download just the small piece
that has changed. If you keep a copy of the previous zip files, whose names
have the dates in them, you can decide what new pieces you need. But if in
doubt, just download the whole thing.
