Fancybrowser example : Javascript alert ActiveX control is not registered.

[josa]

Hi
I am just getting started using qt5.

When I open the fancybrowser , I get a messagebox :

Javascript alert ActiveX control is not registered.

This happens when I try to navigate to the url of an IP Camera that uses an activeX to display video.

I am sure the activeX is registered with the host OS because it works in both IE and Firefox.
Any idea on how to solve this ?
Pse be verbose in comments, Qt is new to me.
