Ready and Calculate at the some time in status bar

[Marita]

I have some files that are around 8.5 meg, but when I
change 6 of 12 months from range valued to calculation
mode (dsums), I get the ready and calculate at the same
time status. What causes this, and how can I fix it?

Thanks for any help.
