Is that addon enabled for all of your toons?

If it is, I'd suggest visiting the IRC on www.isboxer.com.

You can export your settings (copy to clip board), and be sure to use the option which hides your account names. Then paste it all on www.pastebin.com, and have it save it for a month (believe the options are 24 hours, a month or forever). Then copy the URL, which can be used by others with IS Boxer, to load your profile and see exactly what your set up is.
