Hi Eric, > 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. yes I'm just using python rectangle_selector.py with the slightly modified script I have sent last time for matplotlib-svn and additionally comment out the 'button' - keyword argument for the release 0.99.1.1. The only difference between the two runs is whether matplotlib-svn is found in the PYTHONPATH or not. > 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. I'm baffled, too. That was what made starting this thread and hope for an explanation, what I'm doing wrong.
