When did this change?

It used to be that from a persons profile you clicked the "Click to send an E-Mail" link below their picture and it opened up a wee window for you to type in your message and then click send.

Now it opens up a window with another link in it which says "Click to send an E-Mail" again, and when you click this it opens up your email client and the persons email address is in the "to" field.

Not a complaint in any way. Just wondered when/why it changed.
