First of all be very careful using from "module" import * or you will have name conflicts. Tkinter is made to be imported this way and i do it all the time. for the others do.
import tkMessageBox as MB import tkFileDialog as FD or whatever floats your boat. Secondly i hear all the time about problems with fedora distros, so that would explain the issue to me. -- http://mail.python.org/mailman/listinfo/python-list
