Small HTML file won't finish converting
I've just made a very short HTML file to see how the output looks in mobi. The document has only a cover and a one page trial TOC. The HTML is valid.
The same file was accepted and a prc file built by Mobipocket Creator, but the HTML didn't work the way I wanted it to.
But the document won't finish converting with Calibre. The little hour glass has been spinning for about half an hour.
So far as I know I've done everything correctly. What can I do?
