We use the dynamical gluon configurations provided by the MILC collaboration in a study of the charmonium spectrum and + leptonic width. We examine sea quark effects on mass splitting and on the leptonic decay matrix element for light masses as low as ms/5, while keeping the strange quark mass fixed
