It is shown that colour transparency causes nonperturbative colour-sin
glet final-state interactions to have a negligible effect on the produ
ction rate and the dijet mass spectra in e(+)e(-) -->, WW. However, th
e same cannot be said of nonperturbative colour-octet exchange, for wh
ich we show that there are indications of observable effects, though w
e are unable to present precise estimates. (C) 1998 Elsevier Science B
