Yes, apparently the code importing that stuff got removed: http://svn.python.org/view/python/tags/r27/Lib/subprocess.py?r1=79064&r2=82504 FWIW, STARTUPINFO(), STARTF_USESHOWWINDOW, and SW_HIDE were/are undocumented in both Python versions and thus shouldn't be relied upon. They can be accessed via Python's win32-specific modules instead (see diff). Cheers, Chris -- http://blog.rebertia.com -- http://mail.python.org/mailman/listinfo/python-list
