The latest svn version is now working with Python 2.4.4, Python 2.5.2 and Python 2.6.0 on Linux (Ubuntu AMD64, Debian i386) and Windows XP. On Windows the multiprocessing module requires ctypes and pywin32 under Python 2.4.4. Some of the examples aren't working correctly under 2.4 and 2.5. Jesse is looking into it. Christian
