We report first results for spectral functions of charmonium in 2-flavour
QCD. The spectral functions are determined from vector and pseudoscalar
correlators on a dynamical, anisotropic lattice. J/psi and eta_c are found to
survive well into the deconfined phase before melting away at T<~2T_c. Current
systematic uncertainties prevent us from drawing any definite conclusions at
this stage.
