I just tried a transparent button on top of a swf and it worked. I made sure it was in front of the swf in Lectora (below it in the left pane). In the swf on the Parameters tab of the Properties, add a new parameter that is wmode on the left and value is "transparent" without the quotes. It worked for me.I just tried a transparent button on top of a swf and it worked. I made sure it was in front of the swf in Lectora (below it in the left pane).
