i have a worksheet with formulas in 15,000 cells; i have set the calculation to maunal so that you have to press F9 to calculate the sheet. \
sometimes, it takes 45 seconds to calc the whole sheet, other times, it takes 5 minutes. how do i clear the cache, or what do i have to do so that it calcs 45 seconds each time.
i don't want the application to think, it would be better if those 15,000 cells can be returned in a fraction-of-a-second. any ideas/tips? thanks.
