Hello Marc, first, a big thanks for your work. Using Proformell is a real pleasure !
I have a strange problem with the same "font size button", also with the last version of your style.
It's working but the PM popup appearing each time I click somewehere on the board (even if there is no new PM message).
In overall-header.html, if I change "T_TEMPLATE_PATH" to "T_SUPER_TEMPLATE_PATH", PM popup is not working at all and the font size button is not working anymore.
Surely, I make a mistake, but i don't find it
