the pages, while others get the same blank columns. The columns show i
Print Preview, I have reset the print area, still nothing. Any othe

I think I'm having the same problem. Columns A and B just suddenly went
missing completely, and there's a vertical line between C and D (just
slightly heavier than the usual column border).

Does anybody know where they went? And how to avoid it in the future? The
page breaks appear when they normally would if the columns were still visible.

Help!!
