I don't know why but during the last few weeks my Excel has started to react
strangely while being closed / shut down. Most probably due to some very
common option / checkbox being used.

When I click the Larger "X" button on the Upper Right corner, instead of
closing the application only the current worksheet closes. In other words,
even if a single file is opened and even if no work is performed, when I
press the "X" button, the application instead of closing down completely
closes only the blank sheet workbook?

Your help shall be appreciated.
