Front Page Layout Broken in IE7

The right-side of the site is falling below the left side in Internet Explorer 7, which is caused by the lack of “display:inline” tags while using floats (a very common IE bug that causes the margins to double in the direction of the floats). I would try adding this to your css file:

.panel-2col-stacked .panel-col-first{
float:left;
width:50%;
display:inline;
}
.panel-2col-stacked .panel-col-last{
float:left;
width:50%;
display:inline;
}
