    I have a KendoUI app running in a Windows Server 2003 environment and access only to IE 8.  The DataViz charts (bar, line, pie) work in 32-bit but not consistently in 64-bit IE8.  They show the text and the labeling, but no graphical representation of the data or background grid.  If you scroll the mouse around the chart area, you can get the mouseover labels to display too.

    The browser is being launched from a Windows Forms VB.NET (framework 4.0) 32-bit application via a browser navigate call, which opens the default browser:
    Me.uiWebBrowser.Navigate(url, "_blank", Encoding.Default.GetBytes(postString), "Content-Type: application/x-www-form-urlencoded")

    The reason for the x-www-form-urlencoded is to pass credentials via a form POST.

    Here are the two scenarios for 64-bit where it does and does not work:
    1) Run the navigate command as-is opens a new browser window (no other browser windows open) results in the charts not rendering graphics.
    2) Open a browser window (64-bit) then running the navigate command results in successful rendering of the charts.

    Any ideas?

    Hi Adrian,

    The problem is most probably connected with the security settings of Internet Explorer / Windows Forms application to which we do not have control. In the troubleshooting section of the documentation you can find more information about the issue and a set of suggested actions that you may take.
