My experience was similar, and the work-around I found successful was
to launch xemacs from rxvt/bash, rather than from the Task Bar or
Start Menu.  I spent a fair amount of time attempting to discover
whether there was an environment variable which accounted for this,
but failed.

If you're _really_ obsessive (like me :-( about launching from an
icon, compile the following and point the icon at it.

Hope this helps,

   int retval;

   memset (&start, 0, sizeof (start));
   start.cb = sizeof (start);
   start.dwFlags = STARTF_USESHOWWINDOW;
   start.wShowWindow = SW_HIDE;
      
   sec_attrs.nLength = sizeof (sec_attrs);
   sec_attrs.lpSecurityDescriptor = NULL;
   sec_attrs.bInheritHandle = FALSE;

   if (CreateProcess (NULL, "c:\\cygwin\\bin\\bash -c \"/usr/local/bin/i686-pc-cygwin/xemacs -f gnuserv-start\"", &sec_attrs, NULL, TRUE, 0,
                      NULL, NULL, &start, &child))
   {
      CloseHandle (child.hThread);
      CloseHandle (child.hProcess);
   }
   else
     exit(1);
   return retval;
