The problem is that Tkinter has its own mainloop, just like Qt and
these are unlikely to get along.  If you did something like so:

 import mayavi
 v = mayavi.mayavi()

you are likely to get Tkinter windows that never update.  One possible
way around this is to periodically call v.root.update() in order to
allow Tkinter to run its mainloop.  However, this might not work at
all and you might end up with errors or crashes.

cheers,
