We have been working for some time to address a confusing issue when using FX Equation on the Mac.
The issue expressed itself in the following way. The first time you used FX Equation to create an equation, pressing the green tick/check mark would return to Word and paste the equation into the document. The second and subsequent times you used FX Equation, pressing the green tick/check mark would just return to Word and nothing would be pasted. The equation was on the clipboard (and could be pasted manually) but the behaviour of the green tick/check mark was different which was confusing for users and frustrating for us.
The problem has been fixed – but not by us.
We always suspected that the problem was external to FX Equation but recent events have confirmed this. We recently updated our computers to the new “El Capitain” release of OSX. We also accepted another of Word 2011 for Mac’s critical updates. One or both of these updates has fixed the problem. Unfortunately we do not know which one (and would love your assistance in determining which one fixes the problem!)
If you have been battling this FX Equation issue, let Word update and see if that fixes the problem. If not, try updating to the new (free) OSX. The combination of the two should fix things up!
