> I get this when triggering any client JavaScript function which in

> This has all been working fine on previous machine.

> I'm running Win XP SP3, IIS 5.1, getting the error in IE 8 (and in IE7

> My solution is Visual Studio 2005, ASP.NET 2.0/C#.

> My set up is as follows:

> Have the AjaxPro.2.dll in my Bin folder (version 9.2.17.1), all
> compiles and I can reference it etc.

> The onload of my pages has:

> AjaxPro.Utility.RegisterTypeForAjax(typeof(AjaxMethod));

> My C# class is called "AjaxMethod".

> I have extracted the following from my web.config regarding AjaxPro:

> <configSections>
>         <sectionGroup name="ajaxNet">
>                 <section name="ajaxSettings"
> type="AjaxPro.AjaxSettingsSectionHandler,AjaxPro.2"
