I use Today() in my worksheet. It is a volatile function and since I have a
number of cells dependent on it, it may be one reason for slow calculation in
my workbook. I'm thinking about having the function in one cell and running
a startup macro to copy the value to another location and using that for all
dependent cells. Will that help with calculation speed, or since the Today()
function still exists in the workbook, it will not change anything?
