I'm using CR2008 on a Windows 2003 server, running ASP.NET 2.0.

I have a CrystalReportViewer control on a page, but the GroupTree panel comes up blank in IE, where in Firefox & Chrome it displays the accurate GroupTree. Here's the control element. I can provide more details/code/screenshots if needed. Thanks for the help.

<cr:CrystalReportViewer runat="server" AutoDataBind="true"  ID="viewer"
            EnableDatabaseLogonPrompt="False" EnableParameterPrompt="False"
            HasCrystalLogo="False" HasExportButton="False"
            ReuseParameterValuesOnRefresh="True" ToolPanelView="GroupTree"
            HasToggleParameterPanelButton="False" SeparatePages="True">
        </cr:CrystalReportViewer>
