Am I missing something obvious? I can't get line borders to show up around data fields in previes mode. I'm using Filemaker 12 Advanced on Window 7 64 bit.
My simplest test: I drop a field on a new, blank layout. Using Inspector, in the APPERANCE tab, I choose LINE = SOLID, any width > 0, color = black, all 4 line edges selected. The borders appear fine in browse and layout views, but they don't show up in preview mode or on printouts. Manipulating a text box the same way works fine in preview and printouts. Manipulating a data field this way in earlier Filemaker versions also worked fine in preview and printouts.
