This has come up recently in the Microsoft Community as well.



Generally, picking a suggestion given by Word's spellchecker will not change anything more than the particular error you are correcting at that particular moment.

There is an option in the AutoCorrect dialog box ("Use suggestions from the spelling checker") which may add the spelling error and its replacement as a new AutoCorrect entry. It has been suggested (by MVP Suzanne S. Barnhill) that this only works when there is a single suggestion available from the spellchecker.
