Disappearing Seek Bar Handle

So I have a flash file I’m working on. I have an FLVPlayback Component inside a movie clip called mcVideo. I have that clip set up with a MainVideo class which sets the player and all the controls.

Everything works except that I do not receive a seekbar handle, ever. I get a seekbar that shows the loading progress, but the handle never appears. Whether I create an instance of the seekbar in the AS3 class or if I drag an instance of it onto the stage of mcVideo. The loading progress always shows, but never the actual handle.

It’s driving me crazy because this is a fairly simple thing. I can’t figure out what is whacking it out.

Can anyone help???
