#2964: edited MathMenu.js in MathJax.zip and commented out code which caused problems:

if (MENU.msieFixedPositionBug) {
MSIE can't do fixed position, so use a full-sized background
and an onresize handler to update it (stupid, but necessary)
div.width = div.height = 0; this.Resize();
attachEvent("onresize",this.Resize);
} else {

otherwise, use a fixed position DIV to cover the viewport
bg.style.position = "fixed";

}

...
