DESCRIPTION:In order to discuss the stability of four–quark states agains
 t dissociation into two isolated mesons we shall present in this talk an e
 xact method to study four-quark systems based on the hyperspherical harmon
 ics formalism. We shall apply it to several physical systems of interest c
 ontaining two heavy and two light quarks using different non– relativisti
 c quark-quark potentials. Our conclusions mark the boundaries for the poss
 ible existence of compact\, non-molecular\, four-quark bound states. While
  QQ¯n¯n states may be stable in nature\, the stability of Q¯Qn¯n state
 s would imply the existence of quark correlations not taken into account b
 y simple quark dynamical models. The possible role played by confining int
 eractions not factorizable into simple two-body components will be discuss
