Some people have noticed that older versions of WorldClient don’t support newer versions of Internet Explorer. WorldClient does some browser identity and version checking due to browser-specific support for the Lookout theme.
Luckily the fix is simple: You’ll need a plain text editor (use notepad, don’t use your usual HTML editing tools unless you’re sure your tool won’t mangle WorldClient’s tags, and definitely don’t use Word).
Open the globals.js file, located at:
[%Path to MDaemon%]\WorldClient\HTML\LookOut\globals.js
var is_ie55up = (is_ie && !is_ie3 && !is_ie4 && !is_ie5);
var is_ie6 = (is_ie && (is_major == 4) && (agt.indexOf(“msie 6.0”)!=-1));
and add this after it
var is_ie7 = (is_ie && (is_major == 4) && (agt.indexOf(“msie 7.0”)!=-1));
if(is_ie7){is_ie55up=true;}
After that, you should be good to go!
