    Hi Guys
    Slight problem that seems to be getting worse. Sometimes on start up I get a black bar one inch from the left, approx 4 inches in diameter running from the top of the screen to the bottom.
    The Apple 'logo' plus all the finder 'words' appear on the right hand side of this black bar.
    The cursor will not go beyond the black bar. It's as though it hits a wall.

    Any help would be appreciated. I have a feeling apple would love something like this and love handing me a huge bill afterwards

    heres a pic:

    thanks again in advance
