Internet Explorer 7 is mostly a good experience. Yeh, it's ripped off some of Firefox's features, but that's what Microsoft do well.
But what on earth is this dialog box about? I tried to paste into a field in Google Maps and it popped up. I understand that Microsoft is getting a little paranoid about security these days, but of course I want to allow the webpage to access my clipboard, I just hit CTRL-V! Oddly enough this doesn't happen on all websites, so perhaps Google Maps is doing some odd scripting when I do a paste. Who knows, but please someone fix it!
