Forum:Clicking to join Chat opens two windows

I'm from the RuneScape Wiki and when I click to join Chat (From the wikia bar on the top of all pages, whatever it's called), it opens two windows. One small, another normal sized like every other page I open. Also, sometimes it doesn't do this, but most of the time it does. My browser is Safari. — Haidro (talk) 12:05, December 6, 2012 (UTC)
