Calculation Delay problem
I have a calculation field A, where A= C-B
And field C is a calcualtion field as well, if I enter a data to calculate C, then A will be calculated automatically.
Now I got a delay in calculation, if I enter the data, field A does not change unless I scroll up and down or clicking the box in layout interface.
What could lead to this problem and what shall I do to get rid of this ?
