Popup Blocker

Everybody knows now more on the next Windows XP Service Pack 2 including a new version of Internet Explorer.

The main new feature is the popup blocker. But do you know that this function will be disable by default, and turn on only at the first popup.

Silly no ? I know a lot of users who will click on the No button, and again having their popups coming all the time.

IMO It will make sense to do the opposite, no ?

And apparently SP2 will include some tools against spyware. Someone has the details on how this is done ?
