Perhaps it's only a version issue that you cannot set a window title (fig.canvas.set_window_title('title')) for a figure when it's in interactive mode. I'm currently working with LeapMotion which right now can only work with in python v2.7 and mpl v1.4.3 which co-depends on numpy v1.6.1. I have tried newer versions of both numpy and mpl and it doesn't like python 2.7 and LeapMotion, both of which are necessary.

Is there a workaround for this or do I have to settle for "Figure1?"
It's not the end of the world, of course, but it's a nice customization!

edit:
not an interactive mode issue. still exploring the actual issue. sorry for the wasted issue!
