bad magic number in pyc from unix to windows

[Martin Franklin]

Hi,

Has anyone else seen a bad magic number error when using pyc files 
(created on a unix box ) on a windows machine.  I am using python 2.0
on both unix and windows.  The only difference is I didn't compile the
windows version myself.

I deploy me applications with pyc's only (my bosses idea!) and I would
like
to deploy only one version..

Any idea's...

TIA
Martin
