Hi Intersoft

I am using "Intersoft WebUI Studio 2009 R2 for ASP.NET".
I am facing problem in closing the dialog windows.
I have been using WebDesktop and within it I am using a page with the code mentioned below.
Now this page lists the user's emails and the user can view an email by clicking on a link and it will open up in another child window. The child window opens up fine but it does not gets closed.

Also, in case if I make IntegratedToDesktopManager="false" instead of "true", the window closing problem disappears but the color and theme of the window changes from its parent window to the default OS window theme and the buttons within the window stops functioning.
