Have you defined a browse sequence that spans the entire TOC?
No I have not. The browse sequence is disabled. I have forced the navigation mini toolbar to show the previous and next buttons, and I have modied the java script so theses buttons behave like the forward and back buttons in a CHM.
I'm not sure anything can be done about the functionality of how this operates. But for the appearance and seeing the disabled/enabled buttons, you should be able to overcome it by simply editing the skin so that both states present the image of the enabled button.
You could do this in a couple of different ways.
1. Edit the skin and choose the same image for each button.
2. You could just locate the image of the disabled button and duplicate the image of the enabled button and rename it to match the disabled button.
That's what I'm currently doing. It works for the most part. Is there a way I can remove the box that shows around the enabled button when you hover your mouse over it?
I'm unsure I know exactly what you are talking about. Can you post a screen capture?
