Sorry - all methods of resolution in the MS KB article didn't help or were
irrelevant. What did help was to uncheck the "spellcheck as you type" box in
word. Checking it again rbought back the err msg. BTW, the environment used
is MSO 2003 SP3 on WINXP SP2. The error seems to have started after
application os the SP3 for Office :-(
Suggestions ?
