R.I.P. "iChatAgent not responding" bug

Ever since Tiger landed, users across the web have complained about the infamous "iChatAgent not responding" bug. In *most* cases, iChat would work just fine, but in the Activity Monitor a process called "iChatAgent" would stop responding and turn red. Some users experienced crashing issues, but this bug typically was just a worrying blemish on an otherwise smooth-running system. Back in mid-October Apple issued a Knowledge Base article stating that everything was just fine – that we should ignore the issue unless you couldn't log in. Some solution.

Fortunately, Apple's support document that details the changes in 10.4.3 is happy to report (and I concur) that the bug is gone. Dead – at least on the Macs in my household, so I hope the same for you.
