7.1 Patch Update - Chat window too small to read

[Aruss]

I logged in this morning after the 7.1 patch update and the entire UI was tiny because of my graphics. I've been able to scale up the UI to 150% to make things easier to see but I can't increase the size of the chat window! The font has been increased to 14pt but every option I've looked at in the system, character, HUD, or chat settings haven't worked.

Does anyone know how I can fix this as it's raid day so the chat window is important!
