Yeah, so I did the 10.4.9 update, along with the iTunes and Quicktime updates. Now, anyhow I have iTunes set to autoload hidden for me at login. Normally I just use my Apple Remote to play music, etc. However, as I updated iTunes, it required that 're-agreeing to the licence' thing. As it was hidden, if I used the remote at all, it would cause the OS to hang until I manually quit everything and then opened up iTunes... It was quite baffling.
