The Test server (where I have my Summoner) is currently locked.
Looking at the XML, though, it still won't work. You need to add
GetsInput="false"
to the buttons so they don't block the icons.
(And you still need to change the font on the pet name and remove arial.ttf from the zip file.

)
I'll change what's needed and verify it works once the Test server comes back up. Once it's verified I'll attach it here.
