1. open excel options->proofing->autocorrection->smart tag in excel 2007
2. uncheck all item in label data smart tag
3. click ok, then re-open this option, it got mass, not the same with that we
configed before
4. select some of it, then close it, re-open it, it only check the last 3
items, still mass checked
Hope some bright guy give me a hand.
