Weird performance issue when making a discussion post
Scrolling while on the discussion post form page seems to freeze my browser for a few seconds at a time. I don't have this problem on any other Duolingo page (it doesn't happen when editing a post that's already been posted, for example) or on other websites. Firefox 29.0.1 on Windows 8.1.
Update: The same thing happens with the latest version of Chrome on Win 8.1.
