Yes, I open it frequently and I was working on it yesterday. The file was created on this mac and there is no other copy anywhere.
Yesterday, there were problems with msw, and I had to force quit and restart.
The file has graphics and images; I have copied and pasted various online articles into the file, which I am guessing might be the problem (?)
I have tested the functionality of msw b/c I just opened a new blank file (altho not called test).
David: Yes, I just opened it with Text Edit. Now what? I am worried about how to save and protect it.
Thank you! I have the text, which as you noted is the key issue. Formatting in most of the book has disappeared but that is fixable.
However, all the graphics and data charts have disappeared. Is there any way to recover them, or should I just accept that as the trade off?
