Thanks for that Alecs1 have now found it and I am also now able to save backtraces (well the plasma one just let me save it)
The problems that I was having with the wallpaper not saving I and the RSS feed not saving my RSS feeds that I had added seem to have been fixed by my going into the settings and choosing the option to save manual settings. (Don't ask me how I did this as I can't remember, but I found this setting and touch wood, since then my chosen wallpaper and RSS feeds have both been there after a restart of the comp.
