Hi! (sorry for my bad english...)
On Win 7 64 bits: Command-Line CD \Python27 dir C:\Windows\System32\SoundRecorder.exe :==> OK Python.exe >>> import os >>> os.system("dir C:\\Windows\\System32\\SoundRecorder.exe") ==> Do not found the file !!! and os.system("cmd /k") then "dir C:\Windows\System32\SoundRecorder.exe" do not found anyway. But: {Ctrl-Z} in Python then dir C:\Windows\System32\SoundRecorder.exe run OK Therefore, is the problem only in Python? @+ -- Michel Claveau -- http://mail.python.org/mailman/listinfo/python-list
