How can window.closed = true, when the window is open?

Question

Hi all,

I am stepping through code, and I realized I cannot close a window, because the DispHTMLWindow2 object close property is still to true.

    if(winObject.closed != true)
       winObject.close();

The problem is winObject.closed == true, and the window is clearly open.

Any ideas where I can look to figure this out?

Thanks, Grae

UPDATE: I realize this problem may have to do with an embedded PDF.
