I very thin blue line has suddenly appeared vertically on the right side of screen, about 5 or 6" from the edge.  It's going right through everything including the upper menu. What is going on here?  Anyone have ideas? I was just looking at some email at the time.  I restarted computer, but the line reappeared.
