I got some website feedback last night concerning my tips page on
repeating data.  The user was having no problem applying the {REF}
field method on new documents but it wouldn't work on several of his
existing documents.  On further review the failures always occured in
documents containing a TOC.

I have reviewed some simple sample documents that he provided which are
easy to replicate.  In every case regardless if the TOCs are in a
protected or unprotected section the expected behaviour of the
"Calculate on Exit" feature fails.

REF fields are not updated.  Calculation formula fields are not
updated.  Nothing.

If I unprotect>delete the TOC field>reprotect then the expected
functionality of "calculate on exit" is restored.

I realize that on exit macros can be used as a work around, but does
anyone have an explanation or reference to a KB article explaining the
cause of this behavior?

Thanks.
