Here is the solution. David suggested it was a Parallels setting. I searched through the Parallels documentation.
I turned off the option to share Mac programs with the Windows machine. Then I rebooted both the Mac and the Windows within it. Now it works correctly. I think what I did was overkill. My guess is that some form of controlled sharing should be possible. I don't need that feature now so I will not take this any further at this time. My guess is rebooting the Windows might have been sufficient, it was definitely necessary because rebooting the Mac and leaving the Windows suspended didn't do it.
