Setting web browser default

I have Opera set to ask if it's not the default and when I say that I want
Opera to be the default, it is not set by Vista and MS IE remains as the
default.

I have set IE to NOT check whether it's the default

How do I force Vista to allow Opera to be the default?

Seems to be a common problem:
