#1 dependant cells not automatically updated

[phonglong]

updateCells() function does not properly update all the
cells.

If you enter =1, =2, =3, =4, =5 for A1, B1, C1, D1, E1,
respectively, and then enter an equation for, say, C3,
it will calculate the value properly.

Now if you change of the the values in the first row,
C3's value will not update. It will change if you set
an equation for A1. But, no other cell's values are
updated.
