[NUMPY] "ValueError: total size of new array must be unchanged" just on Windows

[Paolo Zaffino]

Hello,
I wrote a function that works on a numpy matrix and it works fine on
Mac OS and GNU/Linux (I didn't test it on python 3)
Now I have a problem with numpy: the same python file doesn't work on
Windows (Windows xp, python 2.7 and numpy 2.6.1).
I get this error:

matrix=matrix.reshape(a, b, c)
ValueError: total size of new array must be unchanged

Why? Do anyone have an idea about this?
Thank you very much.
