And no, it's not a double margin bug issue either. At least, I don't think so since I don't have margins declared for the divs. The width of my languages column here is doubled in IE6 and I don't know why. Thoughts?
Looks like the h1 is set to a width of 150px and ie6 is expanding the languages div to contain it (100px). Try changing the h1 width to something 100px or below.
