After adding a 'progress meter' to the report I am currently working on, I
discovered that the naming of the ranges which I perform first on each sheet
was taking up the vast majority of the time. I was investigating by adding a
timer to the naming procedure, and I discovered that each subsequent running
of the report takes longer than the previous time. The timer results we

Sheet 1: 1.910156 seconds
Sheet 2: 7.582031 seconds

Sheet 1: 2.308594 seconds
Sheet 2: 9.082031 seconds

Sheet 1: 3.507813 seconds
Sheet 2: 14.23828 seconds

I don't really understand what's happening here, since I'm closing the
actual report file each time and just leaving the 'raw data' sheet open which
I use to copy from at the very beginning.

Could someone tell me what's causing the delay in the subsequent runs, and
if there is any way of preventing this increase?

Many Thanks,
Tara H
