Forgive me if this topic has been covered ...I did a search & didn't see it so I'm asking ...my cursor is constantly repositioning  itself when I type causing me to type where I don't intend - it's maddening & really slows down my correspondences.  This is a fairly new issue - it wasn't a problem until about a week ago.  I have an Inspiron 15 M5030 ...if anyone has a suggestion - please don't get to technical on me - TYVM

 

sorry for cross posting - I hit the wrong board first & didn't see how to delete my post
