Version 2.3 fixes three crashes that came up and could cause you a bit of annoyance. They all came within a couple of days of each other which was strange, as the potential for the crashes has been there for some time. Must be one of those weeks!
461: Crash when loading a corrupt or unsupported image in 'Select Pictures' mode
If you added an invalid or unsupported image to the picture list, the application would crash when attempting to set it as the background. This will no longer happen, you'll just get a warning message pop up from the tray icon.
465: Crash when Flickr returned invalid data
Sometimes Flickr would return invalid data when asking for a selection of photos and this would crash the application (it's only happened once but that's enough for me) so now it carries on regardless.
467: Crash when trying to select form a photo set
I inadvertently managed to break photoset functionality (I really should know better), so it should be working again!
