I'm experiencing something of an extraordinary problem (at least from what I'm used to). I have two primary accounts on my computer. When i make changes to my account --account A-- (the wallpaper, for example) the same thing occurs on the other account --account B--. There's also things like when I open Firefox on account A, the theme and bookmarks/extensions are not my own, but account B's. This has happened once before... not quite sure how that got sorted... but it's happening again and I don't know what to do. I'd also very much prefer that this not happen at all. Does anyone have a fix for this? Thanks very much in advance.
