I spent hours working on a presentation in NeoOffice which I sent to my teacher via email. He sends me an email back today saying that the presentation is "empty" and that it has titles but nothing written in the slides. This must be some sort of mistake, I thought. After finishing my project, I saved it to TWO locations, and re-saved it to make sure it would stay the same. Sure enough, I open up the presentation and the entire thing is "empty" as described. What could have went wrong? I know that I didn't delete everything and save over it, because some slides at the end are there, but weren't there until I saved the doc the last time. I swear, OSX is out to get me.
