Actually TCP/IP is faster than Appletalk in any case, and no what you states is not a bug. When you select a server in the Network Browser, notice its listed under Appletalk? yeah, once TCP/IP File sharing is turned on, another neighborhood will show up as "Local Services", there your TCP sharing server will show up. When connecting to a server, the client will only try TCP first if the server is running ASIP or OS X Server , not personal file sharing. Not a bug
