Dear Sir,
The autofill function of Excel seems to be damaged. The following figures
showed what happened when I use autofill function with my PC.




When I click the cell with the wrong result, I found that the function is
correct but the number is wrong as following figure shows.

After I double click the cell with the wrong result, I will enter the edit
mode for the cell. I just press enter, the cell will show the right result
then as following figure shows.

This is really strange. Please help me to solve it. Contact me if necessary.
