Upon launch the JOBS list shows:
Get device information = Finished
Get list of books on device = 57% = 232m 58s
The job never gets to 100%. App just closes without any error or message. Of course I am never staring at the screen if/when 100% is reached.
The books are in the library and I can view them just fine, but unless a portable reader is attached, this job restarts every time I start Calibre.
