Recently I installed OSX Leopard (10.5), iLife 08, also added 1 gig memory and a new battery on my desktop G4. My internet is thru NetZero. Before all the additions I had no problem with the internet. Since adding OSX Leopard I can't open anything in the favorites bar. By clicking on any item the screen remains blank, in the lower left corner reads "Internet zone". That's all. However, in Safari I can browse without any problem. In the Apple System Preferences I have checked everything in the Network Icon. The reply is that my connection is working well. Am I missing something?
