Oh, I see ^-^ That sounds like your computer is well set up - better than most, in any case - many people I know just use one account for the entire computer ;P
Anyway - do you think you could do a screenshot of what you see when you click "Internet Options" in the "Tools" menu and then switch to the "Privacy" tab? (if you can't see any of those, just take a screenshot of what you see ^^ ) To do that, simply press the "Print Scrn" key on your keyboard (it's towards the top right of it), open your favourite image program and click "Edit" / "Paste". After you saved your image, you could e-mail it to me at aaaand I'll should be able to tell you what's wrong ^-^
