today i've tried start minecraft client via command line on windows 7. works! code:

now want create little minecraft launcher python (little gui , on), , know can call command subprocess , popen.
so i've tried popen:

so i've tried it, too:

i think problem windows, there must way solve problem. have ideas?
regards, jonniboy
could try modifying first version adding shell=true popen constructor?
