[comp.windows.ms] WfW Bug - The Final Chapter

a752@mindlink.UUCP (Bruce Dunn) (11/21/90)

In chronological order:

1) I discovered that on my machine, in Word for Windows 1.1, in page view mode,
that if I reduced the margins from the default value of 1.25 inches to 1 inch
and then paged up to the head of the page I could reproducibly cause WfW to
crash with an "unrecoverable application error".

2) I posted a description of this phenomenon, and asked if anyone could
replicate it.

3) I received 6 E-mailed replies which stated that the persons involved could
not reproduce the bug.

4) I posted a message concluding that the bug was probably a quirk of my
machine and that I was dropping the subject.

5) I promptly received two additional messages from people who *could*
reproduce the bug (Charles Bennett with an IBM PS/2 55SX, and Bill Hyde with an
AT&T 6312 WGS (286). (I am using a Sanyo 386 DX).

6) I then received a message from Edward Thorp, in Microsoft Word for Windows
development.  He stated:

    "Yes, this is a bug.  We also found it, but not until WfW 1.1 was out.  It
will be corrected in the next release."

     It's nice to see that Microsoft is apparently monitoring this USENET
group, although it would have been even nicer for Microsoft to post information
about known bugs.
     Thank you everyone for your participation in unravelling this mystery,
even those who sent me mail without a signature line to indicate who they were
(hint, hint).

     All word processors have to save not only the text of your document, but
also information on formatting, the printer that you have selected etc. etc.
In WfW this is saved at the beginning and end of the text.  WfW also has a fast
save mode in which if you for example add a paragraph in the middle of the
document, the new paragraph and instructions on where it goes are appended to
the document.  Parts of your text may thus not be in linear order until the
document is saved with the "fast save" option turned off.

I recently noticed that all my WfW files have some extra stuff either at the 
beginning or the end of the files.  This stuff NEVER showes up when editiong 
the document with WfW, but it does show up when checking the content of the
files by using MORE or TYPE for example.  It seems that this extra data can 
come from duplicating porions of the same file, or be the contents of other
files being edited at the same time, or even random memory data.

Has anybody noticed this strange behavior?  

-- Marco
P.S.:
The version of WfW I am running is run from MS SQL Server

I would guess that you are using the fast save mode, where word just
puts in information about what changed, it does not make a full save.
I would also guess that if you told it not to use fast save, then you
would not see any extra stuff.

Yep, I turned off Fast Save, and the extra stuff disappeared. Thanks to all
that suggested the fix.
