One, possibly trivial, way to fix this would be to change the behavior

James,
The VNCviewer that freezes (in our case) is a Windows 2000 box.
VNCserver is running on an NT box.The symptom is that the cursor
(mouse) freezes on the vncviewer window, only allowing us to move the dot.
We can move up and close the vncviewer window and restart the viewer and
continue
longest time before a freeze has been 3 minutes.

TCP is designed to retransmit lost packets and to drop connections if packet
loss prevents data being transferred, which

severed. If you are actually losing TCP pa

Sorry James, it does happen. especialy in the followings:
if there is high CPU load on the server,
if the server side is very low memory,
if the connection speed is 56k and below.
if there are more than about 20 hoops
