[thelist] Internet explorer selection list counting bug?

Sat Sep 16 04:34:09 CDT 2006

You select your option after select creation (after the loop):
...
//                if(i==2) {
//					window.setTimeout(function() {alert(i); opt.selected = true;}, 0);
//				}
		sel.options[sel.options.length] = opt;
	}
	sel.options[2].selected = true;
