The default behavior of shareaza(with default setting), if it is not connected to the network, then no upload/download with that network. and it is fine to do it on PHEX, since it has been identified quite long time ago, and if Agent name is PHEX and saying G2, force identifying it as Gnutella1 node anyway. but what i am really wondering is not that part. some SKULL based GWC(GWC which support both G1/G2 as separate cache) was saying PHEX is G1/2 node, which means something wrong in GWC interuction, like PHEX might telling that it is G1/2 aware peer. which can cause some problem since Gnutella2(a.k.a. Mike's Protocol) is basically different format(handshake is same). I, very new member of shareaza Developer, do not want any cache pollution.
