Huh. Curious. I saw all red font when I checked with a webbook on Win 10. Four more Win-boxes / laptops running all from XP to 10 upstairs so I'll take a look at those ASAP. On all other machines was just like this MacBook Pro running Yosemite....RED.
I'll fire up some more machines tomorrow while I scratch my head wondering how some coding could go blue on certain machines. Font change, yes. Color though? Hmmmmm.....
