[Plugin: NextGEN Gallery] WMV controls overlapping NGG

I have this problem with NGG gallery: the page where it is located has a WMV file, and when you click on any of the thumbs to load the image in lightbox, the WMV file shows over the NGG gallery. I’ve tried all z-index posibilities, I’ve tried <param name=”WindowlessVideo” value=”-1″> and <param name=”WindowlessVideo” value=”false”>, I’ve tried <param name=”wmode” value=”transparent”> and nothing seems to work. Any idea on what do I need to change in NGG to make it work properly? btw, this behavior happens with all browsers, not only IE family, which will be expectable
