I confirm something similar, Otis, but not random. 100% reproducible: in Firefox on Mac OS 10.9.1 Mavericks. I am not doing anything else concurrently. No inducing activity is needed.
When I run test2.htm from the URL you gave, a small molecule (caffeine?) appears in JSmol. When I rotate that, it disappears. I can rotate a small amount (dragging down, left, up) and see it rotate, but as I continue to rotate to a larger angle, it disappears. When I run test2.htm in Firefox from local downloaded jsmol (drag test2.htm into Firefox), I get exactly the same behavior: It disappears after a small rotation. This was done with 14.1.14_2014.04.10. When I do this local file test with 14.0.11 or 14.0.13, I can rotate freely and extensively and the molecule does not disappear. So I think a bug of some sort was introduced between 14.0.13 and the April 10 version that is online at your URL.
