Button placed inside updatepanel does not work in IE10 (Windows8)

Hi experts,

I face a new problem as I upgraded my OS to windows8. The ASP.NET Button/Imagebutton placed inside updatepanels does not work in  IE10 .It works fine in other browsers. When I placed buttons outside the updatepanel,they worked fine.My server is windows server 2008 with .net freamwork 4.5 and iis7.

Any idea?

Thanks in advance...
