Endnote 8.0 and Citation Insertions into Word 2002 (Win)

This is just a brief note to thank everyone who responded to
my query
both on-list and off-list. 

As many of you suggested, the source of my problem could
have been (and,
indeed was) that I kept the "tracking changes"
enabled on MS Word during
the editing process. I switched that feature off and I am
now able to
insert further citations. Also, someone informed me off-list
that this
freezing problem has since been rectified in Endnote v. 9
even with the
tracking feature enabled, but I'm not able to comment on
that. 

In any case, I look forward to reading the correspondence in
this forum;
it's very useful. 

Best wishes,
Paul J. Scalise
