• Added support for free themes from 24HourWallpaper.com. If you are using one of their wallpapers we listed previously, consider downloading the new versions for improved image quality.

Changes:

Fixed serious bug in scheduling logic when switching between day and night.

The reason why the download is slightly bigger is that the app now includes some code which is used by the Windows Store version (which should be released soon, pending certification from Microsoft).

Fixed serious bug where wallpaper didn't update automatically

Fixed bug for users with European localization that uses comma instead of period for decimal point.

Added ability to Refresh Wallpaper from system tray menu, in case it ever needs to be manually updated.

This update contains several new features:

• Now the wallpaper fades when it transitions between images, like Windows does natively
