Hi. I produce invoices in Excel (2011 on my Mac and 2003 on my PC) and in the past, I've saved them as PDFs by clicking on Print, PDF and Save PDF (or occasionally Mail PDF) For about the last two weeks, each time I've done either of these operations, the PDF has saved as a horizontal mirror image. I've checked all the settings and can't see anything checked or unchecked regarding horizontal flip. I've also tried opening the file from within Adobe Reader and also in Profile, but they are still back to front! I'm running Yosemite 10.10.3 on my Macbook and Windows XP on my PC. Anyone any ideas?
