a search engine is a handy thing:
"Sluggish closing of files is probably the single
most common complaint from Microsoft Word
users who upgrade to Office 97. The slowdown
comes from a feature that many
users–perhaps most–don’t even realize
Microsoft Outlook offers a feature called the Journal,
which can track several kinds of events on your
system. By default, one of the things it keeps track of
is everything you work on in Word. Whenever you work
on a document, the Journal records the filename, the time you created or opened
it, and the length of time you've worked on it. You can view the details as Journal
entries in Outlook 97 by choosing Go | Journal or by clicking on the Journal icon
in the Outlook bar to go to the Journal.
The Journal records these entries whether Outlook is loaded or not, and very
likely it records them even if you've never bothered to open Outlook at all. Alas, if
you aren't interested in using the Journal, the time it takes to write the entries to
disk is simply unwanted overhead.
For reasons that aren’t at all clear, the overhead can be virtually unnoticeable on
some systems but annoyingly time-consuming on others. Whatever the
difference is, it isn’t simply a matter of CPU speed and RAM. My test-bed, for
example is a 90-MHz Pentium with 48MB of RAM. That’s severely underpowered
compared with the Pentium MMX/233 with 64MB of RAM mentioned in the letter,
but closing Word on my test-bed with a file open takes only a second or
two–even with the overhead of a Journal entry–compared with the times of over a
minute mentioned in the letter.
Fortunately, if the overhead is bothersome on your system, there's an easy way
to turn the feature off. Open Outlook and choose Tools | Options, then Journal.
You'll see a number of check boxes for items to track, including one for Microsoft
Word. Remove the checks from all of the check boxes and the sluggishness of
closing programs should disappear."
thats all I could find at this point but you can search some more.
