All,
For me, setting subprocess popen argument shell=True helped. That will keep
the console window from popping up but allows any further windows created
by the subprocess to show up correctly on screen. Using STARTUPINFO()
directly made all subprocess windows hidden.
gpl = subprocess.Popen("application",stdin=subprocess.PIPE,
stdout=subprocess.PIPE,
stderr=subprocess.PIPE, shell=True)
So eventually this was a python issue rather than a pyinstaller issue. It
just showed up only when using the application packed as a exe file.
