I'm running the official SL viewer version 3.7.8 (289922) in French and the lagmeter won't open anymore when I go to the Advanced menu to do so. I had the same issue with the previous viewer version. Back then I uninstalled the viewer and reinstalled it but nothing changed. I even tried to run the viewer in another language but the issue with the lagmeter was still there. When I display the debugging stream and try to open the lagmeter, a message saying "lagmeter not registered" shows in the stream. Can anyone help please?
