Subprocess .wait() is not waiting

I am on Windows 7. Python 2.7
I'm trying to have a program run another program using `subprocess.Popen`
import subprocess as sp
args = shlex.split(args)
proc = sp.Popen(args,stdout=sp.PIPE,stderr=sp.PIPE)
out, err = proc.communicate()
But it *sometimes* doesn't wait and the other program -- which generates a set of 14 Excel files -- does not complete before control is returned to the calling program.
Any ideas on what I can do to make `subprocess.wait()` actually wait?
Thanks in advance for any assistance you might be able to provide.
