Normally, I can press F2 on a cel in MS Excel and NVDA will allow me to read and edit the cell contents. Today, this has stopped working. In a spreadsheet I've been using for a week with no problems, I now cannot hear any cell contents after pressing F2. The contents are there and if I make edits and hit enter I can read my edits.However, this is not sufficient for editing prose.
