What version of Adagio Receivables? Version 90A or an earlier version? This is important as the vertical line handling is different.

Does this happen for print, preview, fax and/or email? Your issue may occur for emailed PDFs if the vertical lines are too long and they need to be shortened.

If you are using Receivables 90A, are you using the new 'Extend Thru detail' option on the vertical lines? This should prevent the requirement of sizing the lines to an extra tall length.

What size paper are you printing to? A standard size like Letter 8.5 x 11 or a custom size?

At the end of the day, this one may require the assistance of your Adagio consultant.
