Well, for me the picture is slightly different:
 a) on a PIV machine: no problems, pasting works, piping works
 b) on my PIII (which I used to do the testing):
    - pasting does not work the first time
    - piping seems to work fine now

    I haven't done thorough testing yet, but this seems
    to improve!

Is the pasting problem related with what Hans just wrote/suggested
"I.e. don't switch off buffering halfway into the program, but
immediately after startup"?
((Speculating: maybe a "fast" machine is fast enough to switch off
buffering before something is written to the buffer?))

Many thanks,
