Excel features no longer working

[teagueman]

I am creating a budget template. I am sharing it with two others but they haven't added any restrictions. For some reason, I can no longer click certain features in Excel (such as add border or font color). The workbook does have a macro which locks each of the three tabs when the file is opened but I unprotected the tabs when editing and this problem still happens. If anyone can please tell me why this is happening and how to fix it, it would be greatly appreciated.

has it been accessed by anyone using a trial or not legitimate software package. Obvious thing to do is a full shutdown, then restart (which I would hope has already been tried)
