See Also topics not appearing in IE10, but will in IE9, IE11

Hello all -

Bit of a problem here. When viewed in IE10, the topics associated with the See Also buttons are not listed. Clicking that button does nothing. However, when I've had coworkers do the same thing in IE 9 or IE 11, the topics are listed, as expected.

Any ideas? My concern is that our clients will be using IE10 and thus these buttons won't work. I don't recall changing anything to the output that would cause this.

Thanks!

Barry
