1. Sometimes when I add stuff to the dock, it disipears from it a 1/2 hour later or so. (eg, added dreamweaver to dock, but not there anymore) How can I stop that? 2. The video/screen goes out sometimes. The monitor turns black for roughly 2 seconds before comming back to normal. I know my monitor is not acting funky as it doesn't do this with Windows. It happens at untimed intervals. Why does it do this? Thanks!
