I have made several screen captures of, supposedly, the Canvas website, moving my cursor around the website, but when I watch the recording the only thing that shows is my desktop. My cursor moves as it is supposed to do in my video, and the audio is also ok, but I do not know how to show the screen that I want and not the desktop. 

FYI, I am using a Mac, in case it has any impact on this. 

Thanks very much for your help.
