Comment (by socha):

 Here's the code I tried (extracted from original submission):

 {{{
 import numpy
 numpy.__version__
 from numpy import array
 f = array([1,2,3], dtype='float96')
 f
 f.astype('float32')
 f.sum()
 f.sum().astype('float32')
 }}}

 Here are the experiments I did:

 (1) Removed numpy directory.  Reinstalled numpy from
 numpy-1.0.2.win32-py2.4.exe.  Same problem.

 (2) Removed numpy and Numeric directories.  Reinstalled numpy.  Same
 problem.

 (3) Removed numpy and numarray directories.  Reinstalled numpy.  Same
 problem.

 Site-packages directory now has contents shown below.

 (4) Removed numpy and reinstalled numpy from numpy-1.0.1.win32-py2.4.exe.
 Same problem.

 Note that I did not see this problem on our Linux computer.  However, I
 have seen this problem on both Windows computers that I have tried it on.

 It may be that to duplicate this, you need to install Python Enthought
 Edition--Python 2.4.3 for Windows Enhanced Python Distribution :
 http://code.enthought.com/enthon/

 Perhaps this is due to a conflict with another package?  Here is the
 contents of my site-packages directory after (3) above:
