I am using InDesign 5.5 on a PC operating with System 7. I have a multipage InDesign document that was working fine until today. I copied and pasted a small block of text to a different location. I couldn't see it after the paste, and tried again. The program then quit working and shut down. I reopened it, and the text block still couldn't be seen when I pasted it in the new location.
I exported a PDF, and the text from all 3 text blocks I pasted on the page was on the PDF, but still not able to be seen on the InDesign document. Now, when I try to create a new text block, it disappears immediately. (The box showing the location of the text block goes away.)
I have other InDesign documents open, and they seem to be working fine. Any idea of what is causing the problem?
