I am unable to edit, save, and apply validation code to my custom Python script in ArcGIS Desktop 10.1.

Please follow these instructions and see if you can get them to work:

1) In ArcToolbox, right-click a custom Toolbox and go to Add > Script...
2) Leave the default properties and click Next >
3) Either leave the Script File blank, or pick an existing script, or type the path of a script that doesn't exist, and click Next >
4) Click Finish
5) Right-click your new script and go to Properties...
6) Click the Validation tab
7) Click Edit..., make no changes, save if you want, and close your editor.
8) Click OK or Apply on the Properties dialog.  In my situation, I get the following message:

Testing get_ParameterInfo
initializeParameters Syntax Error: Runtime error
Traceback (most recent call last):

    import _graph

    import numpy

Note that none of these error messages talk about the file I'm editing at the time.  These are all files within the Python installation from ArcGIS Desktop.
