There is some interface weirdness in the gtk3 compiled version of denemo for mac os x. I was wondering where this code is. Can we set gtk_button_box_set_layout(widget, GTK_BUTTON_EXPAND)? I am only guessing. When I hover the mouse over the message the tooltip shows the missing font. It is like the button is just too small or something. It works ok in gtk2 but thought it would be better if I figured this out.
