Ajax ModalPopUpExtender not modal in IE

3 hours, 1 minute ago|LINK        

hi there,

I am working in .NET framework 3.5 with latest Ajax Downloaded.

I have successfully used the ModalPopupExtender many times.

The only issue i am facing is that the Popup is not modal in IE.

It allows the user to interact with controls/checkboxes which are lying underneath.

I have checked almost all forum posts. Please Help and give Precise solution as when i see the demo on Ajax website, the demo is ok with IE.

I have also added meta tag to keep the compatability with ie as:

<metahttp-equiv="X-UA-Compatible"content="IE=9; IE=8; IE=7; IE=10"/>

I have xhtml doctype in the masterpage as,

<!DOCTYPEhtmlPUBLIC"-//W3C//DTD XHTML 1.0 Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<htmlxmlns="http://www.w3.org/1999/xhtml"xml:lang="en">

Please help
