Hi, thank you for reporting your issue.

谢谢你附上的视频! 视频确实显示了一个奇怪的行为，但我不太确定这是否是Spine的一个错误。当你按下鼠标的后退键时，它似乎将Ctrl+Z视为已按下，但就我所做的尝试而言，只是做一个撤销操作，并没有重现这个问题。有没有可能在你按下鼠标后退键后，Ctrl键仍被视为按下？这个问题是否发生在Spine以外的软件上？

Thank you for attaching the video! The video certainly shows a weird behavior, but I am not quite sure if it is a bug of Spine. It seems to treat Ctrl+Z as pressed when you press the back button of your mouse, but just doing an undo does not reproduce the problem as far as I have tried. Is there a possibility the Ctrl key is treated as if it is still pressed after you press the back button of your mouse? Does this problem occur with software other than Spine?

很抱歉我的解释让你感到困惑，但我认为你没有按键盘上的Ctrl键，我猜测你的鼠标上的后退键的处理方式与按Ctrl+Z相同，因为视频显示问题发生时，撤销按钮被高亮显示。然后我怀疑，如果修改键由于鼠标故障而被按住，它可能会有这样的表现。

无论如何，我想重现这个问题，但不幸的是，我没有带后退键的鼠标，所以我想看看Spine团队中是否有人能重现这个问题。
如果你找到了除使用鼠标上的后退键之外的方法来重现这个问题，请让我们知道。

Sorry that my explanation confused you, but I didn't think you were pressing the Ctrl key on your keyboard, and I guessed that the back button on your mouse treated it the same as pressing the Ctrl+Z, because the video shows the undo button was highlighted when the problem was occurred. Then I suspected that if the modifier key was held down due to a mouse malfunction, it might behave that way.

Anyway, I would like to reproduce the problem but unfortunately I don’t have a mouse that has a back button, so I'll see if anyone in the Spine team can reproduce it.
If you find a way to reproduce the problem other than using the back button on your mouse, please let us know.
