tkinter app won't start on wmaker startup

[Mirko Koenig]

Hi

When i save session with hwindowmaker all applications that are open will
be startet at the net restart of windowmaker again.
Only my tkinter app is not recognized by windowmaker and so not started
at startup

What code have i to write that a X windowmaker can remember the app?

someone told me to write:

root = Tk(className="appname")
root.title("appname")

But this didn't work

Thanx for help
