I am on a PC using Windows XP and InDesign CS2. When I have embedded graphics and delete a blank page spread at the beginning of my InDesign docoment, the graphics disappear off the screen. They're still there; they print, and they show up in an exported PDF, but they disappear off the screen. If I delete a page spread later in the document (after the graphics), the graphics do not disappear. Even if I save, close InDesign, reboot my PC, re-open InDesign, and re-open the file, the graphics are invisible on the screen but visible in print-outs and PDF files. Weird, huh?
