Why are wallpaper images not displayed correctly (black bars etc.)?
WaterWall uses DIBs (device independent bitmaps) instead of DDBs (device dependent bitmaps). DIBs are loaded faster and are more flexible. Depending on your Windows system and graphics driver (NT and/or older drivers) DIBs are not fully supportet. Choose Miscellaneous / Files from the WaterWall options sheet and uncheck “Use device independent bitmaps (DIBs)” to solve this problem.
