Hi, I have tiger installed on quite a few computers, I love the new RSS screensaver and the itunes artwork screensaver. However on some computers these screensavers are NOT installed. I tried google but no one has been able to shed any light on this, is it a system requirements issue? The computers it works on are dual 1.25ghz machines. This machine doesn't even show it as an option, it is a dual 450mhz with 1gb ram. any ideas as to why I can't find these missing screensavers?
