I know my problem has to have a relatively simple solution, it seems when I am typing  as I am typing letters will not stay in order, sometimes they go to the beginning of the line or in the middle of another word.  How do I remedy this please?  Also the page jumps when of course it should not be.  I was in an area recently where one can make changes to the touch pad and did increase the width o f the black horizontal line that follows each word, that is when  my troubles began.  It is doing it constantly while I am trying to type this.  Any assistance would be appreciated.
