The issue comes up for me because I will shortly be involved in
troubleshooting a botched conversion of a 97 db to a 2000 db; searching the
KN for entirely different reasons I came across this article. My trouble is
that I have almost no knowledge of the principles involved (what the heack is
the/a "v-table"?).
The article sets the context initially as an issue of automation but the
context is not retained throughout the article, and I am not sure if the
problems arises only in automation situations.
