Well did a little searching and tried what had been suggested to others, but nothing has worked BUT to disable nUI.
Upon login I noticed font was larger than I had set it. I like font size 14, and it keeps being set to font size 16 upon loggin in, or doing a /reload.
I disabled all my chat addons(Phanxchat, WIM, and elephant) and logged back in and font sitting at 16, resized it to 14 and did a /reload, font back at 16. Log back out, disable nUI, log back in and font size is at 14. So logged back out re-enable my chat mods and log back in, font still at 14. Log back out, re-enable nUI and upon log in my font size is back to 16.
I have tried setting font smaller with nUI enabled and reloading and that didnt help. Tried setting font lower with nUI disabled followed by a reload to make sure it save the setting and then log out and re-enable nUI, and upon log in its back to 16.
I also checked my chat-cache.txt file and it is showing the font size should be 14. Not sure what else could be causing it, because from what I read on these forums nUI isnt supposed to be doing anything with the font size unless something changed with this last update.
