Mike,

It looks like that helps, fixing the window resize behavior, but zooming 
and panning still do not work in the original example given by João Silva:

import matplotlib.pyplot as pl
import numpy as np

x = np.linspace(0.0,1.0,100)

pl.semilogy(x,x**2)
pl.axvline(x=0.5,ls='--',color='k')
pl.show()
