How about simply avoiding recursive updates.
Add this line to your __init__ method:
self.reentered = False
In your viewdata method, put this at the start:
save_reentered = self.reentered
self.reentered = True
and this at the end:
self.reentered = save_reentered
while the update call becomes conditional on not being reentered:
if not save_reentered:
self.root.update()
Of course, this is all a total guess, I really know nothing about TKinter.
