Animate animation not playing in Chrome

There is a Captivate project with Animate animations in it.  These animations play when the project is hosted on Internet Explorer but do not appear when the project is played in Chrome.  The developers wanted to delay the Captivate next button until the animation finished and added the following code to the project-  

window.parent.parent.window.cpAPIInterface.pause();

window.parent.parent.window.cpAPIInterface.play();

Would appreciate any ideas on how to fix this.

Thank you,

Susan
