Why are there IRCOps talking in my status window?

Those comments in your status window are called Wallops, and they are a way for IRCOps to talk to each other without being in the same channel or doing a lot of private messages. You see them because you have set your usermode to be +w (which stands for wallops). Wallops were originally designed to be a quick, nasty way for IRCOps to talk to each other about important server-related matters, and they still do use them for that from time to time, but now wallops are mostly used by the servers or the services for reporting G:lines or HACKs after net.rejoins. Sometimes you'll see IRCOps fooling around in wallops, and if you get tired of seeing it, simply type: /mode yournick -w

NOTE: this only applies if you are running mIRC, but it is asked so frequently I thought it would be a good idea to include it.
