pdf-tools to read PDFs in Emacs, and am pretty happy so far. However, I've found when I modify, and then
eval-buffer my configuration file, the PDFs I opened earlier with
pdf-tools get put back to their first page! This is highly annoying behaviour, and I'm not sure how to fix it.
For reference, all the config file contains that relates to pdf-tools is the necessary
(pdf-tools-install) to ensure that it becomes operational.
