Scroll bar to the right of the program window?

For the Wogglebug, the scrollbar appears to come and go, depending on his IP address.  There are a number of reasons why, but the Wogglebug is of the opinion that some users are given slightly different versions of Khan Academy, as a way to test new features.

Regardless, the scrollbars can be removed.  For HTML projects, use code to this effect:

parent.$("body").css("overflow", "auto");

For PJS, use this:

(function () { this.$("body").css("overflow", "hidden"); }) ();

Thanks, I'll be sure to try that out.
