how disable the next button on playbar on one specific slide

So, as usual, things that look impossible using the published captivate documentation are possible with a bit of splunking in the captivate output.   In this case,  here are a few useful nav bar show/hide combinations

The general form to hide the button is:  

$("#" + "buttonID").css("visibility","hidden")

to show the button is:

$("#" + "buttonID").css("visibility","visible")

Button IDs:

Forward  -  next slide button

Backward  -  last slide button

FastForward -  Fast Forward button

AudioOn - Audio Button

Exit - Exit button 

Play - play button

Rewind - rewind button

paybarSlider   - playbar 

an example is:   

$("#" + "Rewind").css("visibility","hidden");   // hide the rewind button

To use these, just add an advanced actions that call these one-liner javascript functions, and Boom, your're done. Note this is Captivate 9...

I don't believe there is any way from within Captivate to show and hide individual buttons on the navigation bar. If you don't mind, you can hide the navigation bar entirely while the video is playing and then turn it back on when the video has finished playing. I don't remember whether the system variable cpCmndShowPlaybar was in CP7 or not. If it is, the easiest way to do this is to:

1. Load your video on one slide as a Multi-Slide Synchronized Video. Ensure that the slide timeline does not extend beyond the video and that the video is the only object on the slide.
2. In the slide properties for the slide above, set the On Enter action to: Assign, then drop down the list and choose cpCmndShowPlaybar and in the With field type 0 (zero).
3. When the video finishes, Captivate will move to the next slide automatically.
4. On the next slide, set the On Enter action to: Assign, then drop down the list and choose cpCmndShowPlaybar and in the With field type 1 (one).
