Not remembering last book opened etc.
As of yesterday afternoon, my 302 has decided (full battery or not) to not remember my last opened books. This is applying to books on the internal memory itself, not the SD card. As well, when returning to the book through the library interface, it does not remember the place in the book either.
This was not a problem through yesterday morning, and seems unrelated to its' periodic not-able-to-read-external-memory-card issue.
