check whther ajax is enabled in IE6

[mhn]

Is there any way to check whether IE setting "Script ActiveX controls marked safe for scripting" is enabled on a client?

If it is disabled in IE6 then a lot of javascript errors occur:
1. Exception thrown and not caught, Code 0; Line 5, Char 352 in my.jsp
2. 'A4J.AJAX' is null or not an object
3. 'LOG' is null ...

I would like to display a message or an alert that the security settings are too restrictive. Is there any way to do this ?

Hi, I have the same problem: A4J.AJAX is null or not an object. But the most stranger is that this problem occurs just with one IE7 version, the 7.0.5296.0

Somebody can help me? I´m using: rich-faces 3.3.1.GA

Thank´s,
Andre.
