Office 2003 Access Table "Date Last Modified" Property

I am trying to use the "Date Last Modified" property of a table in a VBA module. I have noticed that when I change the data in the table and press save, the correct time and date has been applied to my table. However, if I change the data in the table and close the table with the "X" in the upper right corner, the data is saved BUT the Date Last Modified entry has not been updated. Furthermore, if I change the table data via a form, the same thing happens, i.e. the changes are saved to the table but the date and time has not been updated. It seems that this field is not very useful if the correct date/time of the last modification is not applied. Any assistance would be greatly appreciated. Thanks
