I am trying to update my ichat because its been a little problematic and when I try to put it on my hard drive there is a red exclamation saying:
"You cannot install iChat Update (Universal) on this volume. This volume does not meet the requirements for this update."

last year I had a new hard-drive installed that is much larger. Could this be the reason and what can I do about this? A person was contacting me through
ichat even though he wasn't on my buddy list and the ichat was turned off. Every time this person IM'd me he turned on my ichat. What is that about?
