When I double click an Excel file in Explorer, it does not boot up. Rather,
Excel starts but does not load even a blank spreadsheet. It is likely a set
up parameter but I can't find it.

I also would like to know if there is a way to alter text in other adjacent
cells when a single cell is changed. For example, when a date goes past
current I would like to change the other cells in the row to red. Or if a
check box is selected indicating a task is complete, I want to strike through
the other cells in the row. Any help would be appreciated.
