With help from folks here, I've written a short code to open another workbook
as my primary workbook opens. However, it does so in the existing window.
The other workbook just has reference data, is password-protected and, in
this context, just behaves as a nuisance.

I'd like it to open but otherwise stay lurking in the background somewhere.

I'm using workbook.open, and checked the command but there isn't an option
to tell the 'called' workbook to stay minimized.

Should I essentially treat this step as somewhat of a subroutine? That is,
would an act like placing the cursor in the workbook I'm actually using cause
it to come to the front again?
