That's one of the problems with macros. They can kill the clipboard.

You could check to see if something is in the clipboard and not touch the
calculation mode. But then you do lose what you want to do.

I have the following two events in my workbook to turn calculation on and off
when the workbook is activated and deactivated.

Private Sub Workbook_Activate()
Application.Calculation = xlCalculationManual
End Sub

Private Sub Workbook_Deactivate()
Application.Calculation = xlCalculationAutomatic
End Sub

The problem is that this prevents users from copying from another Excel
workbook and pasting into the one with the code. I am assuming it is because
when the VBA fires, it is emptying the clipboard.

Is there a way to make my workbook calculate manually, while leaving any
other workbooks that are open calculate automatically, and be able to paste
back and forth between workbooks?
