最近更新了新版本。发现一个操作变了。就是原来取消选中的方式是点击鼠标中键，现在变成什么了哦？ 
3.7.xx版本操作问题

对不起，您遇到了麻烦。 您之前说过，您可以使用鼠标中键进行操作。 你在谈论哪个行动？
Sorry you are having trouble. You say previously, you could do an operation with the middle mouse button. Which operation are you talking about?

嗯，现在已经解决了，这个问题。我之前是靠使用点击鼠标中键来取消已经选择了的目标（例如骨骼，图片等）。现在好像只能使用键盘上的Esc键来取消选中了。谢谢官方的回复。
Well, now it has been solved, this problem. I used to use the middle mouse button to cancel the selected target (such as bones, pictures, etc.). It seems that I can only use the Esc key on the keyboard to cancel the selected target. Thank you for your official reply.
