I tried some other pdf files and those converted relatively fast (less than 1 minute), but I have two that seem to create problems.
I could provide one of them to the developers, but only as private submission and ONLY for development and programming purposes. It's a book that WAS available in digital format, for free, but now the online version has been retracted. Only printed version is to be found.
Thank you.
EDIT: - just noticed this:
- I cancelled the conversion job and I closed calibre, but pdftohtml.exe (actually 2 processes with this name) were still running until I closed them forcefully.

The progress shown for Calibre conversions is not linear, it works in phases so you will see progress sit at 1%, then it will jump to something like 22%, 47% is another place it has a big think.
I don't normally convert PDF's with calibre, I've found that I get more consistent results from the Mobicreator program, and its faster, it creates prc files that calibre converts faithfully to epub. To get a reasonable epub still requires editing, but its fairly predictable so I use some editor macro's.
But I just ran some calibre PDF's to EPUB conversions - they only ran for a few minutes each - only one of them appeared to start pdftotml - it gobbled up one of my four processors - MsMpEng never got above 2%.
This is just a hunch. When I first started using calibre I had some issues with conversions gobbling up my system - I've found that the following settings get the work done and calibre doesn't impact other things - I'm running windows 7 on a 6G I5 with a wd spinning disk drives.
