pmw "about" dialog

[Mathias Palm]

the add_cascade command adds an cascade, not an menu entry. try:

aboutmenu.add_command(label="About", command = dialogue_about)

and it should work. A cascade is supposed to be a collection of entries.

If you can get the source code of python (e.g. the tgz-archives from
www.python.org) do it. In the directory Demo/tkinter/ you will find a few
examples on how to write tkinter applications.
