I can explain why THAT happens.

When your original code ran, you got a pointer to a Word object and
held it. You never did release it. So even though you closed the doc,
maunally or otherwise, Access still had the pointer to Word, and
wouldn't let it close properly.

Remeber that VB(A) doesn't have really good "garbage collection" built
in. You need to release pointers to objects, etc explicitly to keep
from having weird things happen.

Why is it weird? Word is a separate application, so when you create a
Word object, you are opening Word. Unless you explicitly close it
again in your code, it will stay open. That's why, if you are not
careful, you can get hidden instrances of it running.

Think about it this way, if you opening a recordset in code, would you
just exit your procedure without at least setting the recordset ot
nothing? So why would Word, (or Excel, or Powerpoint, or any other
automation server) not need to be treated the same way?
