Fixes for problems found by users after launch, and a new way to see your wallpaper while you choose it. Fixed a problem that could stop ClipWall from opening. If the menu bar icon had disappeared and clicking the app did nothing, this update fixes it. Fixed the desktop turning black instead of showing a wallpaper. This could happen when no clip was set, or when a clip could not be played. ClipWall now tells you when a video cannot be used, instead of adding it and showing a black screen. Matroska (.mkv) videos cannot be played and need converting to MP4 or MOV first. Adding a video that cannot be played no longer replaces the wallpaper you already had. New: a slider in the Library makes the window see-through, so you can watch your wallpaper playing while you pick a clip.
