Thanks @Dennis! Is the fix to force a reboot or something like that? And in the future would it be helpful to you if we were to notify you as soon as we encounter it? (since it wasn't familiar to me this time, I waited a few days before mentioning it in case it fixed itself).
Also, I want to agree with @DJMcMayhem "ridiculously useful" comment: I originally thought of TIO as just a cute way to have people try Chapel before installing, but have been amazed at how incredibly valuable it's become to us as a means of showing people examples, illustrating bugs, or communicating about a code pattern in a way that doesn't require making sure everyone has the same installation, flags, etc. Thank you!
