At times, I get this strange looking cell in the middle of a worksheet. It
overlaps into the middle of three adjacent cells: to the right, lower corner
right and the bottom one and has a fat line on the top and on the left.
Cannot erase, or delete it, neither through highlighting and clicking
"delete", nor through trying to make it a normal cell by highlighting it with
the format (brush) ikon. What is the purpose of this formatting and how does
it appear? How do get rid of it? Thanks
