Minor bug: On https://www.javascript.com/try https://www.javascript.com/try when submitting more than one command a horizontal scroll bar appeared and blocked my view of what I was typing at the bottom of the console. (Making the console unusable.) I fixed it by sticking overflow-x: hidden; onto the element's style. A bodged fix, but the bug should probably be looked into. Using latest Chrome on Windows 7.
