Minor CSS issue with layout

I happen to prefer the 2col-bricks layout. when I first set it up, i noticed that it wasn't rendering correctly in IE 7 (the panes were all laying over on the left side of the page).

So, after doing some poking around, I found that the fix was to make some changes to the CSS. Below, I've included a representative sample, but you need to change both .panel-col-last AND .panel-col-first to 49.9% to make it work in IE 7.

.panel-2col-bricks .panel-col-last {
float: left;
width: 50%; <--***Change this width to 49.9%***
}
* html .panel-2col-bricks .panel-col-last {
width: 49.9%;
}
