So I should miss something because I think what I did is correct ;-)

- I start cygwin using the icon from the Windows 7 desktop
(bash shell is used; full cygwin install was carried out)

- in my .bashrc I do have:
export DISPLAY=3D127.0.0.1:0.0

- the command "echo $DISPLAY" gives in this black terminal:
127.0.0.1:0.0

- I execute startxwin.sh in this black terminal

- from the new xterm opened (white), I execute "wish tmp.tcl"
I get:
/usr/bin/xterm Xt error: Can't open display:
/usr/bin/xterm:  DISPLAY is not set

Where is the problem ?

If I execute: export DISPLAY=3D127.0.0.1:0.0 in the x-terminal (white)
& run again "wish tmp.tcl", I get the same error message...

Thanks, regards, Francois

PS We are two different persons having this same problem.
