 From the little information you've provided, what you're doing sounds fine.
Like you, I know this works.  I use Cygwin's ssh/sshd and it's port-
forwarding with VNC (Tight and "normal") all the time and it works fine
(I'm using it now to type this on my machine at home while I'm at work).
I don't use putty though.  However, the cause of your problem is not obvious. 
You'll need to debug it further.  Sorry.


>P.S. Sorry for my english, I'm italian 


Your English is fine.  It's certainly better than my Italian! :-)
