Whaaaaaa! My collections are gone again.
This time from my NC CM7. It's been 2 weeks since I connected to my PC via USB so that can't be the reason. Between the time I last saw them and noticed them missing I charged the unit, downloaded an app from the market and downloaded a book via Calibre opds. Of my original 29 collections only 2 remain, the one that was open and one other, everything else is pfffft.
Haven't heard a peep from Mantano support since I logged a ticket on 11/26 for the same thing happening on my Transformer.
This is a bad bad bug that needs to be squashed.
