We have used the CLEO detector to study Bose-Einstein (BE) correlations among charged pions produced in the hadronic decays of the UPSILON(1S) and in continuum e/sup +/e/sup -/ annihilations around ..sqrt..s = 10.5 GeV. We discuss different parametrizations of the effect, and find indications that the production of long-lived particles in these events can account for the observed reduction of the strength of the effect. We determined source dimensions of quark and gluon jets. From the standpoint of BE correlations, we see no difference between the hadronization of quarks and gluons.
