Earlier when I used to insert a serial no. 1,2,3,4,5,... I used to write 1 and 2 in the column then after selection both the cells I used to drag them down till the required serial no. BUT now I am unable to drag them as the '+' sign that used to appear on the right-down side of the selected cell is not being appeared. Pls help.
Also tell how to restore default setting in excel 2007.
Thanking you
