My most recent post was the first time I had posted from the computer since the latest update and I was having problems scrolling within the input area for creating a new post. The box would not allow me to see the beginning of the my text and offered no scroll bars and would not let me move up the text with the arrow keys within the text.
I also had to hit create several times as it kept giving me a "needs user" error even though I was logged in at the time. I'm running the latest 64bit chrome on a macbook pro running yosemite.
