strange line showing in IE

on the site I am working on http://3dgraphicstogo.com there is a strange line that shows up at the top that doesn't showup in firefox. I cannot find where the problem would be

Under the logo there is supposed to be a thin white linein the black area, but in IE it adds an extra line between the logo wrapper and the nav wrapper, that isn't in firefox.

Please help me figure out how to get rid of this white line.

Thanks a ton.

Tony

Have a look in your tpl_header.php file, find a line that says

Remove this and see if it cures it.

Thanks for the input but unfortunate this didn't help, any other suggestions?

Working on a Mac with no access to IE at the moment, so i can only guess, but I do notice that your logo image is 152px high, but your logoWrapper is constrained to 148px. This type of contradiction can cause the sort of layout issues which you describe.
