Losing pdfs again

[musoware]

2.3.31 should help with the first issue, since it will now retry finding pdfs and images if it found none (or failed) last time, so should recover if it hasn't quite "woken up" after hibernation the first time you try.

UNC - I have found that drive mapping causes problems if the mapping changes.

It still seems to be "behaving itself" after a further hibernation, so that might be a red herring too. I'll update to the latest version anyway.
