i think my screen saver is the culprit for the line
the screen saver i have is a space scene. planets, space station, astronaut. i just noticed tonite, when i saw the screen saver on, that the line appears to be over the same area as the planet in the lower left corner of the screen. i think it has burned an image into the monitor. i thought screen savers weren't supposed to do that. cheap ass screen saver.
my computer hates the u2 screensavers that came with the elevation and best of dvds. it ferezes temporarily with the buffalo one, and the elevation one crashes the computer when you try to come back from it.
