I just played with putting contour labels on manually (and interactively).
It works fine by just left clicking on the spot where you want a label.
But how do you end this feature? The doc string says: right click, or potentially click both mouse buttons together.
Neither works for me on win32, mpl 0.98.3, TkAgg backend, interactive mode.
Does this work for anybody?

Quick test:
cobj = contour(x,y,z) # x,y,z some arrays
cobj.clabel(manual=True)
