I'm using \in to refer to figures, like in the following:
%%%%
La situazione č schematizzata in \in[structure].
\placefigure[][structure]{Struttura di SC.}{\externalfigure[img/structure][width=.7\textwidth]}%%%% The code has always worked, but this morning the refs in the text are replaced by ?? (while img is correctly displayed, with correct numbering). Any hints? Thanks Best -a-
