Hello, long time reader, first time poster I bought my Macbook in August and recently ran into my first problem. Starting yesterday my Macbook has been acting, for lack of a better word, erraticly. There is a constant, reapeating alert sound whenever I go to enter text. Its almost as if someone is holding down a button (which no one is doing). Also when I enter pull down menus the highlight goes up and down and wont go down to the one I want. It always wants to highlight the bottom one. Also when I open Firefox it opens a propmt to askin if I want to turn on "Caret Browsing"... and wont allow me to close it. And Microsoft word is unusable due to it wanting to open spell check and not want to close it. Major piss off and annoying problem. I have tried everything I can think of. Virus scan, onyx, restarting, shutting down, and last night I even did a full delete of the os. Worked for a little bit then returned. I even tried calling Apple, but unfortunatly they wont help me. My 90 day phone support is over... but im still under warrenty. A little ridiculous. Please help. I cannot use my computer properly. I need to right my term papers and am unable to do so. Thank you for any support at all.
