In the middle of regular MIRC activity, MIRC 6.12, I stopped receiving timestamps for channel messages. All other events receive timestamps however. Any suggestions on how to fix this?

Example:

[00:39:44] * %Sounds whistles
<%Sounds> awwww
<%Sounds> rod asks where i am first
<%Sounds> lol
[00:40:09] <Limerick> lol

It just doesn't want to highlight other ppl's messages. /me, join, parts, etc. are still timestamped however.
