As I am using TightVNC, frequently the input locks up: in other words, I can see the remote screen but it will not take any mouse clicks or keyboard input from me. I have tried many things but the only way that I can unlock it is to hit the send ctrl-alt-delete button, and when the ctrl-alt-del screen appears on the remote, I can hit ESC and presto, everything is back to normal.
This has been happening every few minutes to me, yet I have not been able to identify the exact sequence of events that triggers. I am under the impression that it is something related to switching windows on the remote end. I do not believe it has ever locked up if I have been working in a single window and not clicked away (I may be wrong, but that is what I believe).
It is very very frustrating and definitely did not happen as frequently in previous versions.
Please let me know what additional information I could gather (besides a reproducible way to cause the failure, which I have not been able to do so far).
I am running version 2.7.7 on both client and server. Both client and server are Vista 64 machines. However, I have been experiencing this bug through the last several versions. It seems to be worse with 2.7.7
My network connection is quite good. Both client and server are on Verizon FIOS. There are very few hops between them. Ping time is under 20ms and I can reliable push 20Mb in either direction. The connections seem stable because I can leave SSH sessions connected for days at a time without ever losing a connection.
