Hi - I have a spreadsheet that I have used for years in Excel for Mac. It's nothing fancy but over the last month the text values that i have in Row 1, no longer show up when the cells are aligned to 45 degrees. The values are still there, if I select the cell but they do not show up anymore. I thought this might be due to an update but I have updated to a number of new versions since and its still happening. When i send the file to anyone else, the values show up correctly with the same 45 degree alignment. Any suggestions?
