CollapsiblePanelExtender flashing panel during loading IE8

[Cindy Lee]

I don't see the same problem in firefox. Everytime it loads the page
it flashes. Code below. Is there a bug in IE8?

<cc1:CollapsiblePanelExtender
ID="cpe" runat="Server"
TargetControlID="Panel2"
CollapsedSize="0"
ExpandedSize="150"
Collapsed="True"
ExpandControlID="ImageButton2"
CollapseControlID="ImageButton2"
AutoCollapse="False"
AutoExpand="False"
ScrollContents="False"
TextLabelID="Label1"
CollapsedText="Show Details..."
ExpandedText="Hide Details"
ImageControlID="Image1"
ExpandDirection="Vertical" />



<div id="div_login">
<aspanel ID="Panel2" Width="400px" runat="server"
BackColor="Black"
height="0px"
overflow="hidden"

>

<asp:Label ID="Label_error"
Visible="false" runat="server" ForeColor="#CC0000" Text="Bad email or
password"></asp:Label>
<asp:UpdateProgress ID="UpdateProgress2"
runat="server">
<ProgressTemplate>
<asp:Image ID="LogoImage4"
ImageUrl="Images/ajax-loader_flower.gif" runat="server" />
&nbsp;&nbsp;<asp:Label
ID="Label_Ver" runat="server" Text="Verifying..."
ForeColor="#3399FF"/>
</ProgressTemplate>
</asp:UpdateProgress>
<br />
<asp:Table ID="Table2" runat="server"
ForeColor="White">
<asp:TableRow>
<asp:TableCell>Username:</
asp:TableCell>
<asp:TableCell>
<asp:TextBox ID="TB_un_email"
runat="server" Width="140"></asp:TextBox></asp:TableCell>
</asp:TableRow>
<asp:TableRow>

asp:TableCell>
<asp:TableCell>
<asp:TextBox ID="TB_password"
TextMode="Password" runat="server" Width="140"></asp:TextBox></
asp:TableCell>
</asp:TableRow>
</asp:Table>
<br />
<asp:ImageButton ID="IB_log_submit"
ImageUrl="Images\log_submit.jpg" runat="server"
OnClick="ImageButton_login_Click" />
&nbsp;

<asp:ImageButton ID="IB_log_cancel"
ImageUrl="Images\log_cancel.jpg" runat="server"
OnClick="IB_cancel_Click" />
<br />
<br />
<br />

</aspanel>

Thanks, but it's still flashing. I'll probably just use model popup
extender
