No but it might take more than a minute to recreate what was there when the book is viewed again

What does that mean - does it mean open in the calibre viewer, or open in the relevant OS default viewer - e.g. PDF in Acrobat.

The .exe's I haven't highlighted, are the command line programs shipped with calibre.

Which OS are you running -Linux, MacOS or Windows?
