Lexar 4GB SDHC
All books were added as drag and drop from files on computer. I did not use Calibre.
It worked well until 1.9.11
When I reformatted the card (adding only a few books) and did a factory reset on the KT and updated to 1.9.11 again it immediately exhibited the same issues of not reading the card or bumping back to the home screen after a few page turns on any book on the SD card.
I took a chance and bought a new KT for my wife today. I have just turned it on with the SD card inserted but did not update the firmware which is 1.9.9 and the same books and SD card are now working fine.
Therefore: It is something in the firmware that changed in 1.9.11 update and remains the same in 1.9.12
