This unfortunately does not directly solve my problem, because the whole
point is that I want it *inside* the error routine: i.e. if there is
ever an error, and a word document is still lurking invisibly behind the
scenes, then make it visible.
However, your suggestion gave me the 'third way': use a separate
'wordalive' variable that is set to to true whenever I start a new word
object, and release it whenever I make that word object visible. Then,
when I have an error, just test the 'wordalive' variable, and set
loWord.Visible if appropriate.
So thanks, your suggestion got me there in the end!
