The following code aims to allow data input into the spreadsheet, and
then close it as soon as possible, rather than keeping it open, so that
others can also input data.
When opening the workbook, you get a warning message that you should
aim to close it within 10 minutes.
Then, 10 minutes later, you get a message box suggesting to exit ans
save the workbook.
All this works fine.

PROBLEM
If you close the workbook in less than 10 minutes, the workbook reopens
itself to display the warning "Please exit database if not in use."
This is really silly because the operator did the right thing to close
the book promptly, and now the book is open again...

QUESTION
Can I make the macro conditional (to run only if the workbook is still
open)?

Thanks,
Puba
