Simple Zen Template - Support Thread

[Sketchy]

Nice template.

As you suspected, in IE, there is a visual problem on login/signup. One immediate parsing error showed up;

div.order_steps {       /* Is needed for the centering in IE */
    width: 100%;
    padding: 0px;
    margin: 0px;
    margin-top: 10px;
    text-align: center;
}

Add the semicolon(in red).

Being part of the login and something specific for IE, maybe that's to blame.
