in Word XP (under Win 2K) I had a doc with several tables where the
"Heading Row Repeat" didn't.
I checked and re-applied the setting, no joy.
The tables were not in floating frames or anything 'funny'.
The tables were created by copying the header row from one table,
pasting it into the text further down, and adding rows and applying
text styles as needed. The rows were not alowed to split across ages,
but they were fairly short rows, 2-6 lines each.
None of the styles/paragaphs were set to "keep with next".

The solution I found was to:
1. de-select "Repeat as header row at the top of each page"
2. select the entire table, select "allow row to break across pages".
(had been de-selected)
3. select first row, re-select "Repeat as header row at the top of each
page"
4. select the entire table, de-select "allow row to break across
pages".

The rows then repeat as they should.

wierd- something was stuck...
