Been using version 7 all along by the way.
Did as you said DNSB and with these changes now Kpg.exe refuses to create the tgz file that one adds to the kobo memory. Here is a copy/paste of my modified lines so we are sure to talk about the same thing ...
Disable footer example#replace_zlib = 1205FF4,
Decrease footer examplereplace_zlib = 1205FF4
And here is the line with the font size stuff, I took the liberty to copy/paste the unrelated text that follows immediately so you can tell me that I'm at the right place in the text:
{\n\theight: 18px;\n\tfont-size: 14px;\n}\n\n`
