When we are working on the platform using the Browser Google Chrome and a pop-up window appears with a message saying "Page(s) Unresponsive" there are two ways to fix it:
1. Click on "Kill page(s)".
2. Quit/exit Chrome and open it again; doing this we will close all the tabs open in Chrome, not only the tab where you are working.
*Note: please be advised that this message does not belong to the platform, this is an issue from the browser. In both cases, you will abandon the platform and you will have to start or open the platform again.
