Pmw Inconsistencies -- Any ideas ??

[Mike MacDonald]

I'm wanting to use Pmw for a small project.
I notice that sometimes I can't initialise Pmw.

I've posted some sample code below.

Is there something I'm missing around PYTHONPATH?
I reinstalled and it was OK for a while.
OS is Win2K but I've noticed this on other OS's as well

Very grateful for any comments
Thanks in advance
Mike


Sample Code =================================

import Pmw
##class Gui:
##    def __init__(self,parent):
##        self.parent=parent
##
##        NB=Pmw.NoteBook(self.parent)
##        NB.pack(side='left')
##
##        for count in range(5):
##            NB.add('Test Label'+str(count))
root=Pmw.initialise()
if __name__=='__main__':

    root.title('Test PMW')
    Gui(root)
    root.mainloop
