Excel 2002 SP3

I have several workbooks that have multiple worksheets inside. I recently
copied and pasted several of the sheets from one book to another. All links
and reference in the worksheets of the new book are self contained as they
were in the oricinal copy. The problem however is that the calculation speed
in the original is approx 1 second. The calculation speed in the new
worksheet is approximately 45 sec.
Q. Is there a way to find out what is being calculated? The lower left hand
corner shows the percent of calculation coomplete but does not indicate what
is being calculated.
