Spencer, Under Ubuntu (latest mainstream release, kept up to date) I can't get the back-ground colour to change using the editing settings. All other colours work. Ubuntu uses the Gnome windows manager (and so do I). It might be worth pointing out that the background stays white which is also my system's colour set for everything that's not black (I have texts and window headers black) so it could be a conflict between the system setting and the Mini's, conceivably. I haven't yet tried whether this also affects my Windows computer. I also noted that while I can change individual elements (aside from background) with the changes taking effect after confirming them but resetting to the defaults (because I didn't want light pastel colours if I couldn't also have a dark grey background....) only took effect after restarting the MiniA. I'd be happy to run more experiments if you tell me what to look for. Yours, Kas.
