sIFR flash is in front of dropdown menus

While using sIFR to get nice, clean, scalable fonts on the web, I noticed that because sIFR uses flash replacement, the replaced text was appearing on top of (e.g. z-index) the dropdown navigation menus the site had, which was not the desired behavior. The simple fix was adding: sWmode: "opaque" as one of the options to the sIFR.replaceElement method.
