The best advice is to show her a book, like The Savage Garden. *Why should she believe a bunch of internet yahoos, if she doesn't even believe that you've done your research and know what you're doing?
My father was the same way with me... he never seemed to trust that i was competent at anything. *Even when I got my MS in physics, he still would argue physics with me. *He stopped being so arrogant, however, once I got my MBA, oddly. *Suddenly, then, I wasn't "messing up his computer" whenever I came home, and he actually sought my advice on various matters.
BTW, you MIGHT want to edit the title of your post, and the tone of it, especially if you plan to show her the responses in this thread! [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_m_32.gif[/img]
