Cygwin/X server displays nothing, sh.exe hangs

[Mark Allen]

I have been trying to set up cygwin/X on my laptop, Using exactly the same 
startup scripts & packages that work on my desktop, however it keeps failing 
(been trying for 2 days now).

I run the startXwin.bat script (or my own versions of it), 4 processes 
appear:

Xwin
Xwin
Xterm
sh.exe

sh.exe sits on close to 100% cpu usage until I kill it manually, and nothing 
is displayed on the x server (command line version seems to work, but is 
missing several basic commands like ssh for some reason).

I've looked through the mailing lsit & seen zonealarm can be a culprit for 
these kind of symptoms, I do not have zonealarm installed, the only similar 
program is the mcafee security center & privacy service (which I cannot 
disable). I don't know if these cause the same issues as zonealarm.

The laptop is a dell inspiron 510m.


thanks in advance for any help
