Anyone getting an error in Firefox when using text entry boxes?

I have a number of text entry boxes that are used throughout several lessons.  They work fine in Chrome but produce an error in Firefox as soon as someone attempts to type in them.  Has anyone else experienced this?  Is this a Captivate 9 bug that will be fixed?  An issue with Firefox?  Any way to resolve this other than directing end users to use a different browser?  Thanks in advance.
