cursor moves while typing

[gardenhiker]

when I am typing, the cursor seems to jump back to the beginning or middle of the sentence and I am typing the next word at the beginning or in the middle of a previous word.  I haven't accidentally hit the wrong key or anything and this is very annoying as I have to backspace and hit the end button or  move the cursor (if it is not on the same line)to bring the cursor back to where it should be.  Is there anything I can do to stop this?  I had to bring the cursor back to where it should be 4 times while typing this.  I hope this is the right forum to bring this question to.  thanks
