Hello All,
I just tried to install matplotlib on a WinXP computer, after a successfull install on Linux.
The problem I encounter is the following (transcript of an interractive session):

Python 2.3.4 (#53, May 25 2004, 21:17:02) [MSC v.1200 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import matplotlib
>>> matplotlib.use("TkAgg")
>>> from matplotlib.matlab import *
Assertion failed: ob_refcnt == 0, file CXX/cxx_extensions.cxx, line 1031
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
This work on Linux, and I can not find any hint in the doc to a backend/python interpreter incompatibility explaining this error.
I use  numarray version 0.9 (win installer), python 2.3.4 (as shown in the session transcript), and matplotlib 0.54.2, last windows installer (the 2004/06/08 21:54:42 build which I think correct some problems with numarray)
Now I am wondering if I do something I shouldn't, if my system or installation is responsible, or if it is a bug in this particular matplotlib distribution...Any idea?
Best regards,
