I've run into a very odd problem, where the tables that are created in FrameMaker 8.0p277 are not appearing correctly once the book is made into a PDF. The tables appear fine in FM, and at first glance appear normal in PDF form as well. However, if you zoom in on the tables in the PDF, you can see quite noticeably that the horizontal table lines are extending beyond the boundaries of the table, creating little "nubs" down the whole left side of the table. I have no idea what could be causing it, because the tables in FM that are created are simply made with the table designer, they're nothing complicated or out of the ordinary. Is it a problem with Acrobat, or Adobe Distiller? I'm using Adobe Acrobat 3D Version 8.1.2, and Adobe Distiller 8.1.2. I've tried both the "Save as PDF" and printing to file as a PDF out of FM, and the problem exists with both methods. The "nubs" are also visible if you print the PDF on hard copy.

If need be, I can email screen captures of the "normal" tables, and the tables with "nubs" if that will help. I don't know if I can paste them in these messages or not.

Thanks for any help anyone can offer!
