Thanks for your reply, but my purpose in using previewer is to see the conversion log, so I know if my file will upload OK on KDP.
Haven't done this for a while and I used to use kindlegen on my ubuntu system. Now that I have a laptop with Win10 I thought I would try Previewer, but if I can't get a conversion log there is not much point.
I wanted to know if this is a previewer problem or am I doing something wrong? (wouldn't be the first time )
