I have two problems. My MBP 13 inch shows a shared computer in the Finder. It is a Mac computer and most likely my neighbor's. I can access it but only view one folder. I don't want this computer to show up. How do I remove this computer and prevent it from connecting?? Also the icons on my taskbar (the one at the top) are in an order I don't like. Can I rearrange this? Also how do I remove the MobileMe Sync icon from the taskbar?? Thanks!
