 * fixRightHeight()
 *
 * If the nav panel (jt_content_left) gets taller than the right side, the line
 * between them won't go all the way down to the footer (because it's jt_content_right's
 * left border and jt_content_right doesn't have enough content to fill the extra
 * space. This function explicitly sets the height of jt_content_right to fix
 * that problem.
 *
 * @@@ This part doesn't work in IE:
 * If, however, there is enough content in jt_content_right to meet or exceed
 * the height of jt_content_left, the height style element is nulled out and the
 * browser defines its height.
 *
 * This function is also called from navpanel.js::greenArrowToggle() so that expanding
 * and contracting the sections in the navpanel also correct this problem.
