How to fix popup page menu links in Liferay Portal 6.1 EE GA2 for Internet Explorer 9 on Windows 7

Environment

  • Host Environment: MS Windows 7
  • Web Browser: MS Internet Explorer 9
  • Liferay Portal: 6.1 CE GA2 (6.1.1), 6.1 EE GA2 (6.1.20)
     

Issues

  • Popup page menu links for nested pages overlap portlet borders.

  • Popup page menu links disappear when the mouse hovers over them.

Solution(s)

  • Ensure intranet "Compatibility View” mode is disabled.

NOTE: The "Compatibility View" mode prevents the page from rendering correctly.

(i.e. HTML not rendered as expected, JavaScript functions do not behave)
