[Plugin: Wordtube]: Sidebar is not working

I’m using the Plugin wordtube for embeding swf files into our website. Unfortunately the sidebar is not working. The first klick on Play will start the player but there is no chance in stopping, changing the volume or go back to a previous scene.
I can’t show the site because it is not published yet. But If that is necessary for getting the problem solved I can publish it.
Thx
