Local chat doesn’t turn off

Bug or not?

On NIS launch none of the local chat would show as ‘over the head’ -chat for me (except for some npc’s, like familiars’).

Since couple weeks ago I have the ‘over the head’ chat back, but now I can’t turn it off. Turning local chat off prevents the chat messages from appearing in the chat window, but they still show in the Runescape Gold game screen.

I’ve dug through forums and game guides, and while I have found other some other people reporting this issue, I haven’t found a confirmation as to it being a bug. (Which I sincerely hope it is, because I *really* want to hide the chat sometimes.)
