Pages document not responding
I was editing a pages document that someone else sent me, I saved a couple of copies after editing in my dropbox. When I tried to edit the 3rd one it gave a message non solid text outlines were converted to solid lines and when I tried to hit okay it would not respond. I tried to go back in dropbox and open up the original version and it would not respond. I also tried to open up other docs and nothing is happening. I have the new imac and have only had it for 4 days. What is the solution?
