By default, Wallpaper Wizard 2 automatically changes background of a currently active desktop (virtual workspace on your Mac) to a current picture in the Roll. In particular, as you switch among desktops, the app sets the same picture as a wallpaper on every desktop you open. If you set a permanent wallpaper, Wallpaper Wizard uses it as the background on every desktop you open afterwards (Wallpaper Wizard or its Menu must be launched).
If you want to disable the feature, do the following:
- Open the Roll tab and click the gear button .
- Deselect the 'Set wallpapers on all desktops' checkbox.
