flvPlayback CaptionButton Help

I’m using the flvPlayback and Captioning component/skin for some videos. Works great, but I can’t figure out how to have the captions off by default, and use the caption button to turn them on for users who want to see the caption buttons.

flvCaption.showCaptions=false;

hides the captions, but also disables the captionButton in the skin, so there is no way to toggle showing and hiding the captions.

Help!
