Do the books in question have spaces in the file name? I think there may be a problem in that "%20" is being put in where spaces occur, which is correct, but I'm not sure we are handling this correctly. Let me know please. Thanks.

I've created the file in Eclipse Writer but the book port tells me it cannot get the control file. I don't understand what I'm doing, since the opf file is the one I'm choosing. I get the same result when I try to create DAISY files with Kurzweil.
