I coudn't find out how to check this, but it seems to me like your commandline
somehow executes 'cmd /C <commands' instead of 'cmd /K <command>', that
is, it quits every command window after xecuting one command, in stead of
waiting for the next.
What about your user rights? Is your computer part of a network / domain ?
just a couple of ideas, YMMV

edit: checked, can't provoke windows popping up with cmd /C (xp sp2), that's not it
