Duration of Success Caption

Hi All,

I am using Adobe Captivate 9 and have created a SmartShape (with image fill) and using it as a button to display help information when a user clicks on the button. The button is timed to display for the rest of slide and is not set to Pause after x seconds.  There are a number of these buttons on each screen providing help information to assist users as they work their way around a system demonstration I have recorded.  The final output needs to be available for iPADs hence why I have not used rollovers.

Is there anyway to change the duration of the Success Caption from default of 3 seconds ?  I have looked at Edit Preferences ; Defaults ; Object Defaults ; SmartShape and changed the style I am using duration from 3 seconds but does not work.  I have also looked at Object Style Manager for the Smart Shape style but cannot see anywhere to amend the duration.

Is this hard coded within Captivate ?  Is there anyway I can get to the duration and amend ?

Any help greatfully received !
