  We have a very limited knowledge about how the confinement mechanism works in
processes like $\epea\epe\ra\epq\epqa\ggn\ldots\ggn$, when there are identical
colour charges. In this case the partons can be connected by a string or a
cluster chain in several different ways. We do not know if in such a situation
Nature chooses a particular configuration at random, or if some configuration
is dynamically favoured. Also in the perturbative parton cascade we have no
well founded recipe for describing the interference effects, which correspond
to non planar diagrams and are caused by identical colour charges. We have
studied two different models, and are in particular interested in the
possibility that a colour singlet gluon system hadronizes isolated from the
remainder of the state. Using double tagged events with heavy $\epc\epca$ or
$\epb\epba$ quarks, it appears to be possible to find a significant signal, if
such events appear in Nature.
  If this type of (re)connected states appear in Z decays it may also be an
indication that reconnection might appear between the decay products of two W's
in the reaction $\epea\epe\ra\gwp\gwm\ra\epq_1\epqa_2\epQ_1\epQa_2$ at LEP2.
This would be important e.g. for a precision measurement of the W mass.
