When I open Excel, and click on Help>About, it tells me I have version 2002, which is weird because I didn't even know there was a 2002 version.

Unfortunately, CTRL+A does not seem to work for me in this version. I made sure that the cursor was highlighting one of the cells within the data range and it still selects everything.

For example, I have data from A1 to N9, so I put the cursor in cell A1, press CTRL+A, and it selects every single cell, not just the range with data filled in.
