Thanks... I depend on the sparse module quite heavily which is why
it's a problem. (my code that uses spsolve is giving incorrect
results, although no errors). It's probably not as bad as I made out
though - I'm sure I can do a fair bit with 32 bit Python, it's just
more difficult to make it accessible to my colleagues (will have to
install 32 bit MATLAB and they will have to pay attention to which one
they are using).

I would suggest that if I had any influence at all on purchasing
decisions, but as a PhD student I don't. Also MATLAB license is paid
for by central IT, whereas any extra software would have to come out
of group grants. If I wasn't the only person using it there might be a
case, but unless I can get it working on Windows I'll continue to be
the only person using it! (bit of a chicken and egg).
