Disable in-book location saving

Hi everybody. I need some help on this. Every time I save a workbook, the location where I were last (ex cell Z42) is also saved and upon re-opening it again, it opens the sheet to the last location (Z42). So how could I make the workbook and all its worksheets to open at a defined location. ie. A1 for instance.
Hope I was understood and thanks for your help.
