Symptoms

When you open a file in Microsoft Excel for the first time, the file may take more time than normal to load.

Also, when you close the file, you may receive the following prompt:
Do you want to save the changes you made to Filename?

Microsoft Excel recalculates formulas when opening files last saved by an earlier version of Excel.
where filename is the name of the file that you are closing.

Cause

The first time you open a file that was last saved in a previous version of Excel, the file is completely recalculated.

Starting with Excel 2000, Excel forces a complete recalculation of all workbooks that are opened if they were previously saved in an earlier version of Excel, regardless of the link-update status. To fully recalculate the workbook, Excel forces updates of all external references as well, even if you choose not to update when you are prompted to. This process occurs because Excel is updating the workbook calculation chain to the current version.



Resolution

After you save the workbook in the later version of Excel, the workbook will take less time to open on subsequent tries.
