Distorted hotspot isn't working in Flash...only HTML5

I have a project using a distorted hotspot and I've noticed that it's only work with html5. When the browser is using Flash, the hotspot won't turn on. Tested in Chrome and FF with the same results.

Here's a simple example where clicking on the + turns on the hotspot in html5 but not in Flash.

Flash: http://360photopro.com/hotspot-test/index.html?html5=only

HTML5: http://360photopro.com/hotspot-test/index.html?flash=only

XML: http://360photopro.com/hotspot-test/tour.xml

Zipped project (778kb): http://360photopro.com/hotspot-test/hotspot-test.zip

Can anyone see where I'm making a mistake?

Thanks,
Phil
