How often have you had to scroll sideways to read what is written in a frame that is just too small for the job? After all, you don't really mind if you have to scroll downwards because you can remember
what you have just read, and don't have to keep scrolling up again to see what it was all about, however if you are determined enough to scroll to the end of these lines to see what it
says, you will have to scroll back again to see the start of the next line.
