The options for backgrounds are greyed-out and cannot be selected. I suspect it is a setting in REGEDIT, but I'm not sure which "background" or "wallpaper" registry I need to change (nor what the acceptable value would be).
The machine is part of a corporate network domain, but its the only one that is behaving this way. I suppose I could document the registry values from a machine that works and compare them to the one that doesn't, but I'd rather not spend the time if that is not the solution.
thanks!
