[MMTK] A rather annoying newbie question on the netCDF interface

[Roger Jarvis]

Thankyou for responding so quickly.  Following your advice I decided to 
uninstall everything and reinstall according to the instructions on Wiki 
using the most up to date versions of the windows installers.  I now have 
Python2.3.4, numarray1.0, netCDF3.5.0, pywin32-202 and 
ScientificPython2.4.6.  I placed the netcdf.dll in to the 
\\Scientific\win32 directory with Scientific_netcdf.pyd

Unfortunately, Python is still crashing when I do 'import 
Scientific.IO.NetCDF' (or similar) and I'm getting the msg box appearing 
with the error I reported yesterday.

My windows version is XP professional, it's up to date with the numerous 
patches from the windowsupdate site.  I have the freely downloadable 
version of the MS Visual C++ compiler installed.  Let me know if further 
information would help.

Many thanks,

Roger
