Does anyone know if the icon attached below is part of Ext? I'm assuming it is... looks like it could be. (A blue arrow, pointing down at a tiny blue box).
In IE6 only, this icon shows up in my upper-left-hand corner. I have no idea where it comes from, and since I can't use Firebug in IE6 I'm struggling to debug the DOM and CSS. I've never seen this icon anywhere in Ext, but I also don't recognize it from the other icon libraries I'm using.
