Okay, I'm having some problems with my Powerbook. Yesterday, I upgraded Firefox. When re-opening after the upgrade, I had a kernel panic. I restarted my computer and figured I would be good to go. Well, after logging back in, I found that Finder was acting up and I no longer had any desktop icons. Now, clicking the Finder icon in the dock will open a new Finder window just fine. If I go to the Desktop from there, all my icons are still there. So, I decided to restart my computer and see if that made a difference. After restarting, I ran into the same problem. I then decided to trash the Finder preferences and restart again. After restarting a second time, there still were no icons on my Desktop and my sound no longer worked (a problem I've been having after restarting occasionally). I verified the disk permissions and repaired the disk permissions (both took incredibly long... about 45 minutes each probably). When I restarted that time, I reset the PRAM (which is the trick I've found to fix my missing audio). When I got back to my Desktop screen, the icons were still missing but my audio was back. One of my friends recommended that I reset the PMU and that I also run the Disk Utility tools from my Leopard disk upon restart. Do these sound like my next steps? Does anyone else have any ideas? Thanks in advance! Weird... I'm not sure what happened but I fixed it. There was an option selected in TinkerTool that disabled my desktop. I definitely did not check that... but it somehow got enabled. Oh well, good to go now!
