Created attachment 42163 [details] An scalc file showing an unsuccessful attempt to copy sheets I have attached my scalc file. Basically, I made a spreadsheet calendar for January and wished to copy the sheet so I could change it for February. I right-mouseclicked, checked "move/copy" then checked "copy" to end position, and got the attached gray page.
