Thank you for checking into it. I am helping a family member go through an
academic tutorial for a graduate program and the step-by-step instructions
are turned in for a grade. One of the steps is to demonstrate how I was able
to use the Workspace feature. I was very surprised when I was unable to do it
(and I am 100% sure that I did not make an error in the process that got me
to the point where I could not save the four worksheets as a Workspace).

Thanks for any help.
