I'm pretty sure that's the way it's always been. The blue border changes colour when you mouseover it.
This is just out of curiosity, and it isn't a concern as much as an inquisitive question, but has anyone else noticed the blue borders that now line each of the buttons whenever you type out a post? (For instance, the button to make bold text now has a blue box around it, as does the "Insert Hyperlink" button, the text aligning buttons, each of the smileys, etc.) Did something change in the forum options to make those appear? Just wondering.
