I seem to be having a problem with the last iChat update (the one that renewed the encryption certs). I installed it when it first was available using the system updater, but since then I have been prompted to install it again every few days. I never get an error saying it didn't install properly, and my update log shows it as having been installed several times, but even immeadiately after I install it and restart, if I run software update again, it appears on the list still, as if I never installed it. I am relatively new to the world of OSX here, and have never encountered this problem before. Anybody have any hints as to how to make my system realize this update is already installed?
