I was editing a document in Word 2000 (simple stuff) and I came across a black sawtooth line running horizontally across the page. I can't highlight it or delete it in any way. If I place the cursor on it, I get a move symbol. I can move text up or down. If I then move the cursor above the line, I get a symbol with four lines, two long and two short, interleaved. I just want to get rid of the thing.
