#13 editarea - echo on the screen

[Dustin Chase]

As I select lines of code I get an echo and have diffilulty reading the code. As I move further into the code and select a line of code an echo image appears several lines below the line I'm trying view. How can I fix this?

I'm running cPanel via a GoDaddy site. I'm editing php code using Chrome version 61.0.3163.100 64 bit offical build.
