From: Marcopolo on
During spell check in Microsoft Word, if you select Ignore All, Word will
ignore all instances of the word you chose to ignore, not only in the current
document, but also in any other open Microsoft Word documents until you exit
all instances of Microsoft Word on your computer. In addition, after you
save, close, and reopen any of the affected documents, the word you chose to
ignore will continue to be ignored.
In order to reset spell check and have Word flag in a particular document
words you have to use the tool - Recheck Document. This should not be. Does
Microsoft have a fix (patch) for this issue.
