I have a worksheet in which I have copy and pasted several rows from an older worksheet. Two of these cells contain a date, and when I originally pasted them into the new worksheet, the date was automatically changed from 7/29/92 to 7/30/92. When i went in to change the date manually and then subsequently tried to save the file, excel crashed on me and shut itself down. I have tried several times to go back into this file and change the cells, sometime trying to delet them first and every time I try to save it is crashing the program.

Please help!
