Yes, I tried it too. Btw: just few days ago Gabriele told me 'direct doesn't
apply to tcp ports, but maybe I am just confused in what he meant.
btw: you are probably right it can be server dependent issues, as our three
new data files we need to download are from another server, while our files
from the first server we receive data from handles 20KB data flawlessly.
btw: with upcoming rebol releases - are we going to see any changes/addition
to port mechanisms? (Now I don't mean async stuff, but mysterious, record
based port type you mentioned some time ago ...)
Thanks for your help anyway ...
