[AccessD] Let Excel object live?

Even making it visible often won't kill it (you click close but it remains
in the task manager). You have to be careful about destroying ALL object
variables or Excel will probably stick around.

As much as I hate globals, I think this might be a valid use.  You could
make the Excel Application a global in another module, and it would stay
open until you destroy it.  You will need to ensure that it gets destroyed
before the application terminates, or you may end up with a zombie task.  If
your user kills the application with the Windows control box, you may not be
able to intercept it. Unless you make it visible, it will be hard to get rid
of.
