This works for me, provided that I started the server with the -display 
option.  If I connect in with ssh, "echo $DISPLAY" displays 
"localhost:19.0"  Is it possible that the DISPLAY variable is set 
incorrectly? (If $DISPLAY is an empty string, then 2 copies of the edm 
server would have to be loaded for -open to work).

(I'm using edm 1.12.40, but I don't think 1.12.39 is much different, it 
looks as though 1.12.58 might have some relevant changes)

However, if I don't use the -display option when starting edm -server, 
then I get the same error message, unless 2 copies of the edm server are 
running.  I suspect this is a bug in locating the edm server, as edm 
-one -server will allow me to load exactly 2 copies of edm. On the 
production systems, we typically run multiple servers, and use the -port 
option to select the correct one when giving the -open command (rather 
than -display). In either case the -display is necessary for the -server 
command, but not with the -open command.
