Summary: Cascading menu bug on Linux

Initial Comment:
When using post() to display a cascading menu,it 
appears as if submenus don't get mouse events under 
Linux/X. I've submitted some test code below to 
demonstrate the problem.
I'm using Linux 2.4.5/XFree86 4.1.0/Python 2.1/Tcl 
8.3. I've been told that the same code works fine on 
Win2000.

# Code to show problem with cascading menus

import Tkinter

def hello():
    print "hello!"

root = Tkinter.Tk()
frame = Tkinter.Frame(root, width=200, height=200)
frame.pack()


menu1 = Tkinter.Menu(frame, tearoff=0)
menu1.add_command(label="Foo", command=hello)
menu1.add_command(label="Bar", command=hello)

menu0 = Tkinter.Menu(frame, tearoff=0)
menu0.add_command(label="Command 1", command=hello) 
#This works
menu0.add_cascade(label="Menu 1", menu=menu1) 
#Commands used in this menu
                                              #won't 
work

def showMenu(event):
    menu0.post(event.x_root, event.y_root)

frame.bind("<Button-3>", showMenu)

Tkinter.mainloop()
