I am finalizing my IEEE conf paper. I added \usepackage{microtype} When I do that, one of the references is typeset with an extremely overfull hbox. But the log says nothing about any overfull hbox!
Without microtype it's fine. The offending item comes from this: \bibitem{dvbs2-acm} R.~Rinaldo, M.~A. Vazquez-Castro, and A.~Morello, ``{DVB‐S2 ACM} modes for {IP} and {MPEG} unicast applications,'' {\em International Journal of Satellite Communications and Networking}, 2004. Here, the title 'International Journal...' sticks way out into the margin. Any ideas?
