I have CS6 and have had a problem suddenly appear: unwanted, unrequested crop marks appear all over my images and cannot get rid of them. I have gone through all of the available options for activating, deleting, changing, using the classic mode or not, all to no avail. If I close the document and start a brand new document there they are. Re-booting has had no effect. The only good part of this, is that they do not appear on a print of the document showing all of the crop marks. Has anyone encountered this problem and how can it be dealt with? Help very much appreciated.
