Same 8K buffer here -- but since it is Friday I'll wait for our weekly Sunday evening IPL. Thanks!
Next question: why don't we see any sort of error on the TCPIP console when the session is forcibly disconnected due the large screen size/buffer size disparity? Thus sort of thing gets REALLY hard to track down without messages (without even self-defining messages).

I won't be able to recycle TCP/IP until tomorrow. I'll jack up the size and let you know the results.
