LOVE your plugin, I use it on all the sites I develop. Had to wait a while after 3.3's release, but it seemed to be fine after your last update.
However... I've just realized that - while the logo image does now load on the backend - it's no longer linking to the site... at least in my last two installs.
I'm used to popping in to the admin, and right-clicking on the logo to "open in new tab"... but not no more!...
Something you can fix?
