>Well, asking for specific interfaces was one of the tricks to work around IE mangling the HTML, needed for the early versions, and makes sense from the errror you mentioned. But in your first code snippet nothing was done at document level ? Or left out ?

No, and never had to.

This worked well for a year. Then, a Windows update kicked in and never worked since then. A year after, I decided to investigate more on the issue trying to find a workaround. I hope his one will be good for a while.
