web browser script error in CREO 3.0

hello,

I have an issue in CREO 3: my web home page is a Youtube page (4CAD Group - YouTube), and at each refresh, I have an error script:

That's why I try with another page that include the same videos: http://www.4cad.fr/webcast-replay.aspx

and I have another script error:

I modify several CREO PARAMETRIC options, like:

• js_error_policy
• web_disable_js_command
• web_enable_javascript
• windows_browser_type
• browser_limit_to_ie9_mode

I also change few IE parameters, without success.

For information, it works fine in CREO 2.

Someone knows this issue? how can I remove it?

thanks in advance,

Ron
