Is it dynamics or also energy evaluation? Can you do something like

   print universe.energy()

without a crash?

That code was submitted by a Windows user who, if I remember correctly, used 
the Microsoft C compiler. Perhaps the win32api module is not available with 
MinGW or Cygwin, but I am just guessing. Any Python developer familiar with 
Windows should be able to answer that question, so perhaps another mailing 
list might yield more answers.

In a Cygwin environment, one would probably best use the Unix code everywhere. 
But I don't know how to distinguish between Cygwin and standard Windows at 
runtime. For your own copy, try changing all the lines that compare 
"sys.platform" with  "win32" in some way that makes the test outcome change.

There is a very simple problem: I do not have a Windows machine, much less a 
development environment, nor any Windows development experience. All Windows 
installation information and special code was contributed by others. I will 
of course continue to accept such contributions happily, but I cannot really 
help with problems.

The Numeric team includes some Windows developers. I am sure the same level of 
convenience can be reached with MMTK, but I cannot do it.
