So I took a look at my file, and when I turned on the formatting symbols, sure enough, that paragraph had a bunch of extra bizarre crap in it. So I retyped it, and recreated the entire document as a PDF, and uploaded it to LightningSource, and I'm just going to give Steve the $40 for it, because I was supposed to give him a clean document to begin with, and I'm just glad that it's done. I think. They'll generate a proof and send it to Steve today or tomorrow (they're working 24 hours right now, apparently, Xmas rush), and by Monday, hopefully he'll be able to tell me that it looks good and we're ready to order. On the plus side, once we got to that stage with the SH books, they started shipping pretty much immediately. So we're not quite ready for the sigh-of-relief yet, but soon, soon.
Did I mention that Steve's a student? So he's trying to deal with all these revisions and uploadings and such in the midst of classes, and his day job, and a snowstorm, and with multiple computers in different places which can't necessarily talk to each other -- and all over a dial-up to boot? Oh, and now his main e-mail account is eating all the mail I send it because its spam filter has decided I'm not a real person. Yeesh!
We're just damned lucky that I can basically sit at my computer until this project is done.
