I have developed a basic worksheet that doesn;t contain too many formulas and
is around 15,000kb in size. Everytime I try and copy a formula the workbook
runs extremely slow and it says 'Calculating Cells' in the bottom left of the
screen- this can take up to 30-40 seconds to populate 4-5 cells. Is this to
be expected if there are a few formulas or is there anything I can do??

Cheers,
