Oh my head .... OK after much tinkering I got the following to work with .pyw
# scan windows task list to see if GSR is running
f = os.popen('tasklist.exe', 'r')
plist = f.readlines()
f.close
gsr_running = False # scan for GSR program
for line in plist:
if line.split(' ')[0] == 'gmanager.exe': gsr_running = True
Ahhhh ....
