Exit Button Not Working as Expected

I have added an exit button to the end of a Captivate course created via a PowerPoint integration. I used the shape option and checked the Use as Button check box.

I set timing as:

• Display for Rest of Slide
• Changed Appear After to 0 secs
• Unchecked Pause After

Timeline changes:

• SmartShape  button set to 1 second so the user can click the Exit button immediately
• Slide set for 5 seconds

I have tested this in IE11 and Chrome and find that each time I get to the last slide and click the Exit button, there is a pause and I have to click the button 1- 2 more times before the course closes. I need to course to close on the first click if possible.

First click, nothing happens. Approximately 10 seconds later, click again and course closes. Any thoughts on what I may be doing incorrectly.
