The unimplemented traps are undoubtedly Debugger calls when something with networking went unexpectedly. Is there any chance you could install macsbug, and when it happens type:

stdlog will dump a bunch of information to a log file on the desktop, and go will resume execution (which may or may not work, but hey, better than an unimplemented trap. maybe.)

What System version & OT/MacTCP are you using? What server are you connecting to? Apache or a service or?

Control Panels can support copy/paste, but they need to do so explicitly. I haven't added that yet.
