Figure cannot be moved, will go to background (`cmd tab` will not bring window to top).  Within seconds the cursor becomes unresponsive \"beachball\" when over the figure window. \r\n\r\n\r\n**Expected outcome**\r\n\r\nA (non hanging, cmd-tabbable) plot window with something plotted.  This error has persisted for some time.\r\n\r\n\r\n**Matplotlib version**\r\n\r\n- Matplotlib 1.5.1 (latest with `conda update matplotlib`), python 2.7.11 (anaconda distr.), macos 10.12.4 \r\n","author":{"url":"https://github.com/bitworm","@type":"Person","name":"bitworm"},"datePublished":"2017-04-17T23:10:26.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":6},"url":"https://github.com/8505/matplotlib/issues/8505"}
