Excel 2010 is automatically reformatting numbers/cells where a specific number format has already been applied. Whenever I access or modify the cell contents, Excel reformats by changing the number of decimal places to 2. I've already gone into file \ options \ advanced \ and made sure that the option to automatically add decimal places is unselected, but Excel still automatically makes the change. Very time consuming to continue reselecting number formats each time the cell contents are changed/accessed. Any ideas? Thx!
