module error in Vista -- works as administrator

[sawilla]

First, I'm new to Python. I'm getting and error when I run Python
2.5.2 as a regular user in Vista but not when I run Python as an
administrator.

For example, if I type "import numpy" after I launch python from an
adminstrator-privileged command window it loads fine. However, from a
regular-user command window I get:

>>> import numpy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named numpy

Thanks in advance for your help.
