Cannot shift objects off sheet
 

"CANNOT SHIFT OBJECTS OFF SHEET"

I've got this strange message when trying to group several columns using
DATAGROUP AND OUTLINEGROUP.

I've checked
EDITGO TOSPECIALOBJECTS: message: "NO OBJECTS FOUND"

I have tried deleting empty rows and columns and saving the worksheet after
selecting "A1" but with no success.

It looks like to me that the spreadsheet is feed up with data.

Can some one find a more wiser reasoning?
