	Good question.  Wish I knew the answer.

	I noticed this behavior during testing.  I am going through the DOS
for the data blocks, so any weirdness you observe is the DOS's fault (isn't
it always? :-) ).  I can only assume that the ACTION_GET_BLOCK packet
somehow trashes the buffering scheme, perhaps marking buffers as invalid
(which, of course, makes no sense).  I'm convinced MetaComCo is trying to
sabotage the Amiga :-).

	Would anyone at Commodore care to explain this?

	Side note:  I've received a couple of notes (one private, one
public) concerning the size of my .signature.  Odd, thought I, since it's
only 564 bytes.  However, not wishing to aggrevate the net.gods who so
graciously provide me with this (largely) free information source, I've made
a new one, which is 360 bytes.

	So, if you have a copy of the old one, save it; it may become a
collector's item :-).
