Picking text outside of the axes region seems to be broken in matplotlib 0.99.1 and in the latest SVN. This functionality used to work in version 0.98.3. The example code pick_event_demo.py demonstrates the issue. The "ylabel" in the red box is no longer pickable. Is there a "clip_on" or similar setting on the picker that needs to be set now? Below is a simplified version of "pick_event_demo.py" for reference. I also added some text to the plot to make sure that text inside the axes region was still pickable.
Thanks,
