I must admit it beggars belief that Adobe would insert that comment into their templates - and it isn't helped by the fact that DreamWeaver colour coding makes comments drop into the background to such an extent that you have to actively choose to look for them to read them!
I can understand that they want to make users aware of the issue but surely the best approach would be to have a standard IE hacks CSS file that templates link to - at least you would then see it in the CSS styles list and be able to edit it as required.
Madness - how many people have spent hours like me trying to work out why IE refused to move items no matter what you did?
