Why is clicking on any of the four menu items unresponsive? | 为什么点击四个菜单项中的任意一个没反应？

Four menu items
No matter which item I clicked, there was no reaction after the menu disappeared, and there was no dialog box for me to save the file. What could be the reason?

四个菜单项
无论我点哪一项，菜单消失后什么反应都没有，也没有出现让我保存文件之类的对话框。请问可能是什么原因？
