Whilst creating a website design earlier, I decided to take a look at my website in Internet Explorer 7. I copied the URL from the Firefox address bar and pasted it into Internet Explorer's address bar.

Oddly enough, Internet Explorer decided to open the HTML file in my default browser – Firefox. I suspect this is an effect of IE7's new behaviour where it is finally separated from Windows Explorer. Typing C: in the address bar now opens up Windows Explorer rather than displaying it in Internet Explorer.

I actually had an issue with this behaviour when trying to access my school area from home using Internet Explorer (WebDav/Web Folders) and it did a crazy dance.
