I have IE 6.x and I have the same problem. I've been told I should simply install Firefox... bleh.
It was working about 24 hours ago, and now nothing... being that I'm not the only one with this problem, it tells me something likely changed/bugged on the game and not my comp.
I put on firefox but now my scanner doesn't show anything when I know it is picking things up. Please somebody help me! Scanning is what my character does he's intel.
