HTML5 Drop Down Widget on Internet Explorer Issue

When using the HTML5 drop down widget, there's an issue with Internet Explorer. On second entry of the same slide with a dropdown, IE reports an error "Error: Can't execute code from a freed script" and the dropdown will not report a value change.

We found the simplest fix was to declare the variables used by the dropdowns in the base HTML that Captivate exports. In example (put in the head of the index_SCORM.html file):

<script>

var dropdownvariable1;

var dropdownvariable2;

</script>

Please note that this issue occurs in Captivate 8 and 9 with an HTML export.
