using 10.4.3.2 (last updated 18/7/14) on Windows 8.1 on Samsung ultrabook.
So all my notes got eaten - dropbox was syncing lots while it happened, and only my last few notes were visible.
I could scroll through where the other notes were - the location bar scrolled through as i scrolled the text - but nothing was visible. I tried copying and pasting the blankness into word but there was truly nothing there -just space.
i checked on my phone and despite syncing every few minutes, no notes i'd taken on a pc were there, including the most recent ones - the ones that still worked.
So i tried to restart, and now Accordance won't open at all - eek!
