Deployment problem

Hi
I have problems with deploying application to IIS. It works great from VS08 development server, but published code does not work from localhost.
First I have 'Ext' not defined error, which was allready discussed here and was successfullysolved with CleanResourceUrl="false" on all ScriptManagers. Teddious but effective.
Second is AjaxEvents related BADRESPONSE error. I added AjaxRequestModule in web.config, but no result.

Do you have any idea what to try next.

Thanks in advance
