I was told I should delete language files, to help run faster is this true? 2.I tried to download a screen saver (http://www.apple.com/downloads/macosx/icons_screensavers/plasmatubemotionlightscreensaver.html) it them told me to place it in the screen saver file when I tried to do that it said the volume could not be found. any ideas? 3.Any fun programs i should try out?
