Hi,
I have a problem with Cygwin. I am connecting from USA by ssh to the 
Hector supermachine in Edinburgh ( I write "startx" in Cygwin and then I 
use  "ssh -Y  v1acanes AT login DOT hector DOT ac DOT uk" ). Everything works fine, the 
only problem is that the forwarding of the windows is very very slow. It 
takes sometimes also up to 5 minutes to open a new window. I am 
debugging a code with Totalview and it is a impossible to work. I am in 
contact with the Hector support and with their computer they tried to 
run Cygwin under windows and connecting by ssh (exactly like I am doing) 
and they say that x-forwarding  is fast. My version is:

CYGWIN_NT-5.1 1.7.1(0.218/5/3) 2009-12-07 11:48

while their version is:

CYGWIN_NT-6.0 1.5.25(0.156/4/2) 2008-06-12 19:34

So my version is more recent. I do not fell like to downgrade Cygwin,  
everything works well save the slow X-forwarding. Any suggestion please?

Thank you very much
best regards
Alberto
