Anyone explain whats missing causing this error..besides the ovious notion
that black is an unusual color??

raceback (most recent call last):
  File "/usr/bin/Teach2.py", line 375, in ?
    TeacherTool(Tkinter.Tk())
  File "/usr/lib/python2.4/lib-tk/Tkinter.py", line 1569, in __init__
    self.tk = _tkinter.create(screenName, baseName, className,
