yes. and now that i understand what you are trying to accomplish ... :) the problem is in BackgroundDialog::saveConfig in kdebase/workspace/libs/plasmagenericshell/backgrounddialog.cpp it is called when apply or ok is clicked and it unconditionally resets the wallpaper. it probably needs to track when the wallpaper settings actually change. right now it does this: connect(wallpaperWidget, SIGNAL(modified(bool)), this, SLOT(settingsModified(bool))); settingsModified is a generic "something's changed" handler; a new slot could be added that calls settingsModified, but which also tracks that value for the wallpaper itself and if no changes have been made to the wallpaper config, just not reset it. -- Aaron J.
