In the past, I've been able to copy and link cell content from one worksheet
to another by simply copying and pasting from one cell to another. Today I
found that I must select "Link Cells" from the Paste Options buttoni n order
to link cell content. In addition, when I select Link Cells and hit the
enter key, the cell link is broken. In the past, when I hit the enter key
the screen returned to the working cell. What's going on?
