To 'unstick' it, it is necessary to left click. I believe the expected behavior is to only drag the legend while holding the left mouse button. If that is not the case, please close this issue.\n\n### Proposed fix\n\nSample code:\r\n```python\r\nimport matplotlib.pyplot as plt\r\n\r\nplt.plot([],[], label='scroll over me, then move the cursor')\r\nplt.legend(draggable=True)\r\nplt.show()\r\n```\r\n\r\nI believe the issue is that the class `DraggableBase` (at line 1425 of matplotlib/offsetbox.py) uses a 'pick' event to grab the artist, which I believe includes scrolling events. It might be possible to return from a false positive pick by checking that the pick event is a mouse click instead of scrolling at `DraggableBase.on_pick`. Another alternative is to change the pick event to a `button_press` event.","author":{"url":"https://github.com/p479h","@type":"Person","name":"p479h"},"datePublished":"2024-11-14T16:58:20.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/29142/matplotlib/issues/29142"}
