    Issue 1:
    I am using RadWindow to show a modal dialog. In all browsers except IE I get right behavior i.e. you can still see the parent page, just cant click on it. But in IE, color is so dark it hides the parent page. Attached are pictures showing the difference. Any idea why is it happening.

    Issue 2:
    Interestingly I am using exact same code in another page and there I get correct background in all browsers and you can see parent page in all browsers when dialog is open. But when I close dialog window, it scrolls the parent page to the top. Even though there is no refresh or anything on window close.

    Would appreciate any help. thanks.

    Hi, I am experiencing the same problem and found out that this happens when the page is more than 4000px tall... Apparently it is a browser limitation of IE 8.0... I hope someone comes up with a solution.

    Hi guys,

    This usually happens with Desktop PCs / laptops with older version of the DirectX driver or video card. The  problem itself is related to the DirectX CSS filters under IE - we use them in order to achieve a transparent modal overlay in IE. The other browsers do not use that Activex component, as they have utilized pure css opacity, and respectively the problem does not occur.
    In this case I recommend you reduce the page size in order to make the page works properly. Also, you can use a non-modal RadWindow control and avoid using any animation on the page. All of the transparency animations use the same DirectX filters under IE and may cause the same problem.

    Kashif, regarding your second question - how do you open the RadWindow?

    To add to Georgi's comment I also found that these IE settings will do the trick:

    Open IE -> Internet Options->Security->Trusted Sites->Custom Level

    Enable the following ActiveX setting:

    Enable - Binary and script behaviors

    Hope this helps!
