[Tutor] Revving up Tkinter/PMW

[Ike Hall]

Thanks Danny,
I don't think that I'll be able to introduce a new version of Tkinter, as I 
am doing this for a large collaboration, and getting new base software 
introduced takes some time, but I will make that suggestion.  I will however 
look into the prospects for double buffering

thanks

Ike
