Hi! I work as IT in a small company and we are having issues with some web pages in IE 11. The only way they work is to activate DEVELOPERS TOOLS and use as agent IE8. Adding the site to compatibility list does not work.

The problem is that every time the users need to enter this portal (Walmart sales) they need to push F12. Is there a way to leave DEVELOPERS TOOLS settings running?? The "Persistent settings" button is not of help. Once you close the browser, it come backs to regular settings until you push F12 again.

Thanks in advance!!!
