IE conditional stylesheet: modified DD liquid layout 2.1

[traq]

Hello everyone,

I'm modifying Dynamic Drive's Liquid Layout 2.1 to add 10% margin to each side of an extra wrapper for the content section (not the top or footer), thus making it fluidly centered. I'm using an IE conditional statement to change this to a 10% padding on the content section itself.

The problem I'm encountering is the menu (left column, purple) div is not visible in IE until you shrink the browser below 700px or so, and then it's in the wrong place. the layout works perfectly in Firefox.

Test Page
"reset" css
main css
IE css

Any suggestions?
Thanks for your attention, everyone.

changing

#menucolumn{
float: left;
width: 200px;
margin-left: -80%;
}

to

#menucolumn{
float: left;
width: 200px;
position: absolute;
margin-left: 10%;
top: 90px;
}

seems to work on both browsers (with the IE conditional fix). Does anyone else know of a better way?
