Mystique submenu flash/ sv-gallery

I’m using Mystique and the submenu is not playing nice with the Flash image gallery on the page. (SV-Gallery plugin)

I’ve changed the params.wmode to transparent in wp-simpleviewer.php

if ($wp_simpleviewer_options['jsbox'] != 'off') {
				$wp_simpleviewer_gallery_output .= '
				params.allowscriptaccess = "samedomain";
				params.wmode = "transparent";';
			}

but that doesn’t seem to be fully doing the trick.

I think it did change something in that it now shows the submenu background color on top of the flash, but it’s still not showing the submenu itself (only on mouse-over and not very fluently).

Does anyone have a fix?

(I don’t know if a Mystique update will fix this, but I haven’t changed my adjusted Mystique into a child theme yet, so I can’t update yet without losing changes and the menu kinda had to work while I’m adjusting things theme-wise..)
