That sounds reasonable, but I'm still confused. With > the matplotlib release 0.99.1.1 the RectangleSelector works with and without a > reference to it. Was this old behavior somehow unintended?
I don't know. In both cases, are you trying it in a script, and running it outside ipython? Ipython keeps references to inputs and outputs. There haven't been many changes to widgets.py, and I don't see anything that could account for the difference. I also don't see what could keep it alive if you don't keep a reference to it. If the same externally-run script works differently in this respect between the two mpl versions, then I'm baffled.
