10.0. "Clipboard clogged" by INTER::JONG (Steve Jong/NaC Pubs) Fri Oct 13 1989 13:34

    I've run into a strange situation regarding my clipboard.  Using the
    Create menu, I created a book, with its attendant sub-books, 
    catalogs, and templates.  Later it was pointed out to me that I should
    have used the System cabinet, so I deleted what I'd started to use and
    created another book.

    Later on, when I went to purge my clipboard, I found that the cut-out
    icons could not be purged.  I can paste them back onto my desktop,
    where a look at their property sheets reveals them to be incomplete
    files.  I can cut them again, which moves them to the clipboard, but
    there they remain, like a dozen lumps of undigested fat.

    Being an adventurous fellow, I looked at the clipboard directory using
    VMS.  To my surprise, there are three or four files listed that don't
    show up in Interleaf, files I thought I'd cut (and purged) long ago.
    I deleted everything in the clipboard directory, but some few failed to
    leave, either because they were non-empty directories (old books) or
    because the "ACP file access failed."  The undigested files were
    deleted.  But Interleaf still shows them in my clipboard!

    Now, strange as it may seem, I have files VMS sees but Interleaf
    doesn't, and files Interleaf sees but VMS doesn't.  My clipboard is
    otherwise functioning normally; I can cut and paste text, components,
    and documents, and I can purge new things I've put there.  But I think
    that in regard to the files I've mentioned, it's really screwed up.
    
    Here's what VMS thinks I have in there right now:


Directory USER$653:[JONG.DESKTOP.CLIPBOARD_CLP]

$FROM__DOMAINS_TXT_.DOC;1               EMA_GD_BOO.DIR;1    EMA__V3__FDR.DIR;1 
FROM__DOMAINS_TXT_.DOC;1                FRONT_FDR.DIR;1     

Total of 5 files.

    Here's what Interleaf thinks is in there right now:

	Ten catalogs:	CONTENTS
			FRONTCOVER
			GLOSSARY
			INDEX
			PREFACE
			SPINE
			STRUCDOCCHAP
			STRUCDOCCHAP (another one)
			TITLE
			APPENDIX	
	Two other files:NEW_SRM_GLOSSARY
			PUZZLE

    Note that nothing on the first list is in the second, and vice
    versa!

Bette Jean's suggestion to close the desktop helped a lot.  Now Interleaf
and VMS are close to agreement as to what's in my clipboard.  The twelve
things Interleaf saw are gone; the five things VMS saw appeared in the
clipboard.  I was able to purge four of them.
    
	It's still a weird problem.

    
    This same phenomena occurred to me. I tried various methods of deleting
    these files from the clipboard but none of them worked.
    
    I left them there and did not say anything because I thought I was
    doing something wrong and had to rush on to do other things.

The problem is that Interleaf (originally written for Ultrix based systems) 
reads file differently than VMS.  Linked files (the catalogs) cannot be purged 
from the clipboard, instead must be deleted from DCL.    

I've spoken to software support on this and the above explanation is what I got.
It's a bit annoying but nothing that prevents us from getting the job done.
Deleting from DCL and closing the desktop does the trick.

Question:

Please, please tell me how to purge unwanted catalogs/templates from my
clipboard. 

Answer:

You have to delete them from the DCL level.  Not through Interleaf.  Set
default to your clipboard ([username.desktop.clipboard_clp] and enter
DELETE *.*;* -- that will clear the clipboard entirely.  However, it will
not register in the current session of Interleaf.  It will register after
you close and reopen your Interleaf desktop.  If you could do a rescan of
the clipboard, that would probably work, but you can't.
