Scrath

I believe it sometimes works based on when the book was published for some reason and that newer books may have a better DRM protection against this method

The only thing I hate is how sometimes a document compiles perfectly fine on one machine only to utterly fail on another. On the two machines were I had this happen I have Texlive installed so that I wouldn’t have to look up missing packages. Maybe this is a version mismatch error? I have no clue.

Also I had an old document I wanted to compile which used a ‘\begin{justifying}’ tag. I can’t get that tag to work anymore and had to replace it with just ‘\justifying’

Did you ever find out what the books name was?

Not OP but I’m curious about one thing I personally miss with kate.

Do you know if it is possible with kate to keep temporary text files open after closing the program the same way notepad++ can?
