Have used another Python GUI Framework (tkiner, Qt, etc) previously (yes/no is fine)?
yes

You have completed these steps:

• [ yes] Read instructions on how to file an Issue
• [ yes] Searched through main docs http://www.PySimpleGUI.org for your problem
• [ ] Searched through the readme for your specific port if not PySimpleGUI (Qt, WX, Remi)
• [ ] Looked for Demo Programs that are similar to your goal http://www.PySimpleGUI.com
• [ ] Note that there are also Demo Programs under each port on GitHub
• [ yes] Run your program outside of your debugger (from a command line)
• [ yes] Searched through Issues (open and closed) to see if already reported

Code or partial code causing the problem

I'm new to PySimpleGUI. When I use module subprocess and packaged py into exe, it always crash like screenshot below. But when I run my py file direct in cmd, it just fine. So anyone please tell me how to fix it? thx.

Exe file crash on Windows7 when click ok:

SimpleDemoTestSubprocess.py:

import PySimpleGUI as sg
import subprocess

    """ run shell command
    @param cmd: command to execute
    @param timeout: timeout for command execution
    @return: (return code from command, command output)
    """

    prt('runCommand, cmd = ' + str(cmd))

    p = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
    output = ''

    prt('runCommand, communicate')
    out, err = p.communicate()
    prt('runCommand, wait')
    p.wait(timeout)

    prt(out)
    prt(err)

    return (out, err)
