Above does work - but I thought we were supposed to move away from  
Menubutton's

(Can't remember where I read that though)

Sorry Jeff not sure I follow are you saying this :

import Tkinter

t = Tkinter.Tk()
mb = Tkinter.Menu(t)
mbm = Tkinter.Menu(mb)
mbm.insert_cascade("end", label="File", underline=0, font=("Helvetica",  
24))
mbm.insert_cascade("end", label="Edit", underline=0)
mbm.insert_cascade("end", label="Help", underline=0)
t["menu"] = mb

mb.add_cascade(menu=mbm, label="Menu")
t.mainloop()


does not show a different font on your Windows system?
