I remember several people providing mac help here before. The computer having the problem is in SC, but Patty's sent me a couple of screen shots I can pass on to anyone who might be able to point us towards a cause. The lines look like printer overprint, just a group of four offset dashed lines (not solid - more like out of focus characters) that ran across the page layout view in excel (in fuschia). Which then cascade to be visible in the same format or as blocks (still not solid) when she brings other windows forward. help. anyone have any ideas? Kathy.
