The unresponsiveness of your click may mean that the browser is in a state of suspended animation. Please follow this method to solve the problem. Open the browser, click "Tools" - select Internet Options. After opening the options, click "Security" "Select "Default Level" for Internet, Local Internet, Trusted Sites, and Restricted Sites under "Security". After completion, refresh the webpage again, or close the webpage and reopen it, and it should be fine.
