Thanks, we tried that and it would not let us remove that setting. It would
always revert back when the Language dialogue box is closed. We worked
around this by selecting a different language, save and close the document,
reopen it and reset the language back to English. That seemed to kick it in
the pants and it started working.

If the spell checker passes over areas of text and does not pick-up mis-spelt
words it is possible that the text has been marked not to be checked.

To solve this problem do the following:
1. highlight the area which won't spell check.
2. click 'Tools' menu then the 'Language' option, then 'Set Language' option.
3. ensure that 'Do not check spelling or grammar' option is NOT selected.
4. click

The Spell Check should check the area now.
