Hidden Smartshapes over web objects

Hello,

I'm using adobe captivate 9 to produce HTML output.

If i insert an HTML5 web object, everything works good, until i try to insert a hidden smartshape over it that is toggled by a button, then the web object is no longer clickable.

When flash was used instead this wasn't a problem, you could toggle a smartshape (show/hide) and the anmation button still would work.

Any solution for this?

Thanks.
