Javascript error

[Vitaly]

Good afternoon,
Inside RadPanelBar I have button which is redirect to another page:

<asp:Panel ID="Panel1" runat="server">
<telerik:RadPanelBar runat="server" ID="infoPanel" Width="98%" ExpandMode="MultipleExpandedItems" BorderWidth="1px" Skin="Telerik" >

<Items>
<telerik:RadPanelItem Expanded="true" Text="EMPLOYEE PERSONAL INFORMATION" runat="server" Selected="true" Font-Bold="true" Font-Size="13" Font-Names="Verdana">
<Items>
<telerik:RadPanelItem Value="employeeInfo" runat="server" Height="75">
<ItemTemplate>
<div id="formDiv" style="position:relative; left :0px;">
<asp:Button ID="ReqFormButton" Width="215px" CssClass="button" runat="server"
Text="New Shortage Area Request Form" onclick="ReqFormButton_Click" />

</div>
</ItemTemplate>
</telerik:RadPanelItem>
</Items>
</telerik:RadPanelItem>
</Items>
</telerik:RadPanelBar>
</asp:Panel>
When I had old computer Windows XP I had no problem to redirect but when I received a new machine with Windows 7 operating system and try to redirect to the page I am getting javascript error:
Line: 6
Error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near '�'.

Please help me.
thanks so much.
