I agree to a degree about the new script blocking in SP2; Usually it's been a real good thing.

It's annoying when I preview a webpage from my folders on the desktop; especially when there's no scripts running. Not sure what's up with that.

It's also annoying when I try to download files. Yes of course I want to download the file that's why I clicked on the link -- a couple of extra steps later...

On the whole though; yes, I'm glad I've upgraded.
