Nah the trade was just a joke.
I don't have IE6 on my pc so i had to use a online emulator, that one showed the website correctly after this trick.
Sorry i couldn't help you with the problem.
I tested "the fix" on IE 5,5 - 6 - 7 - 8 and the only version that has problems with it is 5,5. (i tested it in IETester0
Strange that it will not work for you. If i understand correctly the problem was that IE 6 chopped the flag.jpg on the left side of the flag right ? otherwise i misunderstood the problem.
