As a result, I thought it was probably still worth letting readers know about it in case they were experiencing it for the first time, or just had not managed to correct it yet.
The most common symptom of this problem is any ActiveX buttons in your spreadsheets ceasing to work. If this has happened to you and you haven't yet found a solution, read on.
The problem stems from a Microsoft security update on 9th December and applies to the 2007, 2010 and 2013 versions of Office. If you have automatic updates switched on, you will have had this update.
The update has caused problems for ActiveX controls and the most visible problem is that existing ActiveX buttons, which you may have in your spreadsheet to run macros for example, just do nothing when you try to click on them. Note that Form Control buttons are unaffected.
Full instructions from Microsoft to deal with the problem are available here:
In most cases, the following will work:
In File Explorer, search for all files ending in .exd, then delete these files (they are temporary files anyway and new ones will be created next time you use the ActiveX controls).
At the Microsoft link above there is also a script that you can run to do this if you prefer.
