When posting on a topic in the forum or typing a blog on a computer/laptop - if you go from a full size web page to a smaller window size, and then back to full window size - the text box stays the small size.
Does not affect when you Create New Topic

Images because words are weird:

Original Full Size ^^^

Full Size - to Small Size - to Full Size | Text Box is still condensed

I noticed this too! Very annoying when typing something long

This is very frustrating - especially when you are referencing another window while writing a forum post and using a split screen. It greatly affects usability of forum posts
