Lost features after Office 2000 update to Office 2003

[Syl]

A few days ago I updated Office 2000 running under Windows
XP pro to Office 2003. I also installed all of the updates.

I have noticed that a number of features in Word don't
appear to work properly. For example, if for a table under
table properties->row I check "repeat as header row at the
top of each page" the header row is not repeated.
Similarly, if I don't check "allow row to break across
page breaks" is allows the rows to break.

I used these features a lot in Word 2000. How do I get
them to work in Word 2003.
