Printing black/white construction drawings. One of my Sheets has very slightly shaded background (scarcely noticeable), rather than being transparent/white. This massively increases the print spooling time (other normal documents print immediately).Anyone else had this puzzle? To clarify: it's the entire printed area--excepting the paper margin--that has the shading, not just the viewport. And I've confirmed that background is set to white in interactive appearances tab.

Select similar is not behaving as it should. I created a pattern of adjoining hexagons using move by points (so all identical by definition, and same alignment). Then I tried to select similar (with size and object checked in the preferences box), but only a few of the hexagons were selected. Can anyone shed light on this strange behaviour? Thanks.
