Any computer literate folks who can help me?I have a laptop I bought in May.Everything has been fine until last week.All of a sudden, my cursor has started jumping around when I type, whether here or in Word or on Facebook.Either it jumps back a few words and starts typing in the middle of another sentence, or worse – everything highlights blue and erases.I googled it, and it seems a lot of people with laptops have this problem and it's a known Microsoft issue.Has anyone fixed it?Do you think it's something the Geek Squad could figure out?
