I have a problem with indesign CC, when opening idml, it attach to every image or text box a symbol over the box in black, like bracket from letters keyboard. I can't clear them and they are printable. My indesign document is useless. it happened only in my indd - export i, open idml again and ... symbols are over the boxea... any suggestion?
What, exact, version of InDesign are you using and what operating system?
