Hi

I wonder if somebody might be able to help...

I have copied the source from "http://ajax.asp.net/docs/tutorials/IntroductionUpdatePanel.aspx" page,  the calender example as per "http://ajax.asp.net/docs/ViewSample.aspx?sref=UpdatePanelTutorialIntro2", but when I execute it in VS 2005 running on AMD 64 (XP Pro x64),  both instances cause a full page refresh!
 

I have tried the following

1) compiled the above source on another machine XP Pro 32bit - worked perfectly top instance updates panel calendar only, bottom whole page!
2) published as per 1) - worked perfectly!
3) published from x64 onto its internal IIS - fails 

 any ideas....

does Ajax function corectly with xp64?
is my machine (xp64) or Visual Studio misconfigured?

many thanks in advance
 

Ok, Ive narrowed it down to the web.config i've got already associated with this website.....

basically i've inherited this website, which used old style .net controls and am trying to add update them to ajax based controls!

ive gotten some controls to work (cascading dropdown etc...), but the update panel still wont (with this web.config)?

does anybody have any ideas what, in the web.config might cause issues?

thanks 

SOLVED:

 comment out : -    <xhtmlConformance mode="Legacy"/>

so web.config now contains

    <!--
    <xhtmlConformance mode="Legacy"/>
    -->
