I'm updating an indesign document that was set by a previous designer a few years ago. When I opened it I noticed there's two yellow boxes with speech bubbles when I'm in normal view, which disappear when I'm in preview mode. The one on the text box moves with the text box, so it must be linked somehow? The other one on the top of the page I can click on but it won't let me delete it or move it. Any idea what they are and how I get rid of them.
