I did check the font box in "filter style information" in the last pass into epub. Don't know if that was needed. Also, I added all the Kobo/Mini specific changes on the mobi to epub pass and not on the original epub to mobi pass. Is that the best way to do the conversion?
Thank again. I'm off to play with some of the other files that had line spacing problems.
You are welcome.
I don't think checking the font box helps in a conversion to mobi or back to epub, as mobi doesn't AFAIK support embedded fonts or numerical font sizes. font-size: 0.77419em; is usually converted to font-size: small; then converted back to font-size: 0.75em; which the Kobo seems to understand.
It seems to be nonstandard font sizes that make the Mini choke anyway.
Oh well, not the most elegant solution, but it seems to work.
