I work in an office with a shared public network. There are multiple versions of Microsoft Office in use. When those of us with the newer version go to delete cells on screen, cells that are off screen go blank. So when you scroll down to continue working on the sheet, the cells are blank view. You can't even see what number row it is, but if you click the cell itself it shows there is something still in the cell. You can save and exit out of the document and go back in and it is fine. How can we stop this from happening because it is happening very frequently? Sometimes we have to close in and out of the documents close to 15 times to finish the work we need to do on it. Any help would be appreciated!
