OK, I tried that.  No difference.

Here's what heppened on the FreeBSD 6.2 system:
$
$ echo $DISPLAY
localhost:1.0
$
$ xhost
Xlib: connection to "localhost:1.0" refused by server
Xlib: PuTTY X11 proxy: wrong authentication protocol attempted
xhost:  unable to open display "localhost:1.0"
$
$ xhost +
Xlib: connection to "localhost:1.0" refused by server
Xlib: PuTTY X11 proxy: wrong authentication protocol attempted
xhost:  unable to open display "localhost:1.0"
$ xterm
Xlib: connection to "localhost:1.0" refused by server
Xlib: PuTTY X11 proxy: wrong authentication protocol attempted
xterm Xt error: Can't open display: localhost:1.0
$



Here's what happens on the FC6 system:
$ echo $DISPLAY
localhost:13.0
$
$ xhost
access control disabled, clients can connect from any host
INET:terry-pc.egizone.com
LOCAL:
$
