SSH connection times out

I regularly log into my 9.3 box via SSH (Putty on Windows) and run
RealVNC through an SSH tunnel. This works well; however, after about an
hour it appears that my connection drops out; Putty will ask if I want
to accept the key again and it reconnects. This would not be a big
problem except that KDE-VNC does not work (I can't type anything in to
unlock the screen) and if I use (which I am) X-VNC the server resets
each time and I lose my session.

Does anyone have any suggestions as to how I could solve this problem
(or what is causing the problem)? I use have used FreeNX but the
computer I am at is basically a kiosk so I have to be able to run things
without installing them (can't use a LiveCD either).

Thank you in advance for any help that is offered.

I might have figured out the issue; it has to do with how Putty handles
keys. I still am lost over why KDE's VNC system won't work. I have all
of the latest updates.

First determine if the problem is caused by Putty or the SSH daemon. Try
connecting with a Linux client, to see if it also drops the connection. If
not, then it's a Putty problem.
