I installed the 10.5.2 update on my PowerMac G5. Everything seems to work fine, except that my desktop icons have disappeared and I open any windows in Finder. When I boot, my dock comes up normally. The various system icons appear in the top right corner but on on a transparent, but I don't have a Finder bar at the top of the screen. If I open an application, I get a bar and everything works normally. In the dock, the greyed "Application Not Responding" message is visible when I right-click on the Finder icon; if I click relaunch, nothing happens. I've repaired my permissions using Cocktail (since I can't navigate to Disk Utility), I've rebuilt my launch database and run all the scripts also using Cocktail, and then rebooted multiple times. I tried downloading the standalone update (353mb) thinking I'd try to reinstall the update, and it obviously downloaded, but I have no way to get it to run (that I know of) since it isn't visible on the desktop. I can see it though by "tricking" the Finder into showing it by going into Accounts in System Preferences and clicking the Add button for Log-In preferences. That gets me to a dialog box/window where I can see all my drives and desktop folders just fine, and the updater file (dmg) is there as well. Any ideas are appreciated.
