or: (for long-running Win32 processes) os.startfile(r'/relative/path/to/app')
http://docs.python.org/lib/os-process.html under linux/BSD/solaris, i've run into situations where PATH and other environmental var s aren't what you expect (they're from the /etc/profile system defaults, not from your .bashrc). I can't remember if anything like that happens in windows. -- http://mail.python.org/mailman/listinfo/python-list
