i really have no ideea if this is a bug or not, but when trying to run a page that uses cufon.js (http://wiki.github.com/sorccu/cufon/usage) on a ie6 page started in ietester nothing happends.
i tried it on a ie6 native browser and it works.
cufon.js is a font replacement thingy.
it's not a big deal but o thought it worth mentioning
