(3) later in that same session, i did my usual'
SAVE.EVERYTHING-to-floppy , and got a break window with the message':'
"Floppy':  Severe Error!  ':  Streams Allocation Error ERROR".  i tried'
reformatting the floppy; didn''t make any difference that i could see.  i'
gave up, did some other things (including RECLAIM, and erasing many'
windows from the screen), and retried SAVE.EVERYTHING-to-floppy.  it'
worked.  about 2 hours later, i received the same error message and'
could not shake it.'

     (3) Somehow, you''ve managed to get a {FLOPPY} STREAM whose PALLOC'
allocation record is missing from {FLOPPY}''s cached directory.  I'
don''t believe there should be anything wrong with your floppy, but'
{FLOPPY}''s info in core is confused.  I''d appreciate more background'
on this problem if you can repeat it.  Probable workaround is to just'
open & close the floppy drive door, which will flush {FLOPPY}''s cached'
directory structure.'
