Remote machine suddenly can't open X display

Hi all

I have been happily connecting to a remote machine (with ssh -X -c blowfish)
for 2 weeks and running X apps over the network.  It has been working very
well, but this afternoon I started getting messages like this:

mwh at Athlon ~ % gedit &
[1] 609
mwh at Athlon ~ % 
(gedit:609): Gtk-WARNING **: cannot open display:

[1]+  Exit 1                  gedit

mwh at Athlon ~ % dx &
[1] 610
mwh at Athlon ~ % Error: Can't open display: :0.0

[1]+  Exit 1                  dx

mwh at Athlon ~ % wish8.4
Application initialization failed: this isn't a Tk applicationcouldn't
connect to display ":0.0"
% mwh at Athlon ~ % 

...and now I cannot run any X apps at all.  I can't remember having made any
controversial changes that would have caused this so I rebooted both my
local machine (OS X laptop) and the remote server (FreeBSD 5.3p5 amd64) but
no change.  

Can anyone advise me where to look to solve this problem?  Error logs?
Environment variables?  (<- my local login .bash_profile contains
DISPLAY=:0.0 and export DISPLAY as recommended).  Diagnostic tools?

TIA

Michael
