When I print from FH 10 or MX I sometimes get a white box around each line of type. The white boxes don't show up in preview mode, only in the printed document. The boxes are not the text bounding box - they're around each line of type. Selecting or deselecting "Display Border" has no effect.

(And by the way, why does FH sometimes display the border when I haven't asked it to? Can I disable the Display Border function?)
