Thank you very much, thats great! It all works fine (its really interesting to see modern websites in outdated browsers!).

But, I've made a small javascript to fix png opacity in IE6 (and possibly earlier) and it works fine on computers that didnt had IE7 installed. Now that I run the script from your IE6, it seems not to work, even though the script is still triggered by conditional comments.

Any thoughts on that?

Again, that you very much, your effort is greatly appreciated!
