In fact, I have observed the the entire Mac may freeze durint that time. All of these sessions have the following in common, so far: they involve Macintoshes talking over Appletalk through a Kinetics Fastpath (2/3 _or_ 4) and Ethernet to a Vax. The protocol could be Telnet, CTERM, or Pacer's PNP. The problem seems to be worse on older Fastpaths on busier networks... but I don't seem to be able to establish the exact cause of the problem. I _suspect_ the Fastpath, but I can't prove it. I know we're not the only site experiencing the jerkiness, but so far Kinetics professes to be unaware of such a problem. Who else has seen this? Is there some way we can establish the exact cause? /kenw
