I had used Shotwell happily previously then updated to Natty last week.
Despite Shotwell showing on the tool bar on screen, when clicked, nothing happened, and it ignored my SD card when loaded.
I read all sorts of remedies and tried everything to no avail. When I next turned on the laptop, Ocelot was available so with nothing to loose, I upgraded again. Still no Shotwell.
Tried all the new fixes and now atleast I have the icon pictures but nothing behind it. When I ran the command to load the log file, Shotwell loaded and all my photos are present. Exited programme, and now nothing. Can anyone tell me where I have gone wrong please.
