No you don't have to. Certain browsers select the line numbers when the code in the frames are highlighted. You can work around this by clicking "Download Raw" on the top of the code frame, and view the source code by on its own. This will open up in the same window. You can click 'back' in your browser to continue on with the EdX Platform.
