Working in InDesign CS6 last night, in "web page" mode. I brought one graphic onto the page, and copied it (alt+drag) 20 times. Each image has the animation to "appear." The file seemed fine last night. I saved, closed the program, and today, if I try to do anything at all, the whole program freezes. Supposedly there are "no errors" in this file.
see Remove minor corruption by exporting and if yo can't do that after opening the file, see Adobe Community: InDesign 6 is crashing when attempting to open a particular document. All others are opening OK.
