Always epubs from an original .doc (most of the times) file transformed using Calibre. I explained in my previous threads the steps I normally do.
I agree with franky, it seems that radomly the device run out of memory somehow. The problem is that with a reset the performance does not always improve and we have to install other firmwares...
I do not know if that helps but when I experience these problems and I reset the device, the system does not remember the page I was reading in the book. Also, the page marks dissapear somehow...
