Calculation Progress Window
The auto-hide Calculation Progress window displays information about the calculation that is running. For general information about auto-hide windows, see Auto-Hide Windows.
If this window is not open prior to the start of a calculation, when you click OK in the Calculate window, it opens. While results are calculated, you can enter and modify data in the System file. You can also unpin the Calculation Progress window if you want to hide it from view. Neither of these actions affects the calculations being performed.
If you wanted to stop the calculation, you would click Stop. However, this does not undo any calculation results that have already been saved.
