I just got a new computer with Windows 7 (64 bit), installed the latest version of Putty, and find that Putty always locks up once I disconnect an SSH session or when I get disconnected (e.g. when the server reboots).
Putty works great until that point and hangs every time on disconnect.
The only way I found to terminate Putty at that point is to kill it through the task list.
Anyone else seeing that? Any known fix?
