I have a powerpoint file to which I have added a large amount of text in the speaker notes. When I opened the file today, the speaker notes were all gone. When I click on the "notes page view" icon, I get a blank page with only the page number at the bottom. Not even the slides are showing up in the notes page view. I've tried to export the notes via the "Send to Word" command, but no notes show up. If I print the notes pages, I get blank pages -- again no slides, just a page number. If I choose View Speaker Notes, I get a blank text box. I've tried changing the Notes Master page but nothing I do has any affect. File Properties - Statistics says the notes are there, which is perhaps the only sign that my notes aren't totally gone. However, nothing I've tried can bring back the notes.
Where did my notes go? How can I get them back? If they're gone, how can I avoid losing them in the future?
I'm running Powerpoint 97 SR-1 on Windows XP Home.
