Welcome to WebmasterWorld Guest from 184.108.40.206
Looks like I'm switching to Yahoo for my searching now.
I just tried it again and the behavior is now a little different. I still can't drag a SERP result to a new window, because nothing happens when I try (no outline of the link appears under the pointer). But I guess that's an improvement from Google rudely taking me to the SERP result as soon as the mouse goes down.
BTWY, I can still drag non-SERP links on Google, such as the 1-10 page numbers on the bottom of the page.
IMO everybody has his own practice on click methods.
I would also suggest trying to command-click on links since that's a really easy way to get them in a new tab or window (if you don't have tabs turned on in Safari they go to a new window). Command-shift-click and it will open behind your current window.
