I can reproduce this easily. It just happens. DECterms and ico seem to be
affected so I can well believe that any X application will suffer. I haven't
used DECnet as an X transport for a while but I think it used to work - or, at
least, used to work better - if it hadn't I doubt I would have built all those
Xservers :-) 

Unfortunately both Steve and I will be away next week (though not togther!) so I
doubt much is going to happen on this for a while. I might get chance to have a
quick look at it this weekend but no promises.
