Sitefinity 7.2 we have a usercontrol that needs a captcha.
I can put this in and it works but it requires a script manager and I can't get around it
<telerik:RadCaptcha ID="captcha" runat="server" ErrorMessage="The code you entered is not valid." Display="Dynamic" ForeColor="Red" ValidationGroup="IsValid" >
<TextBoxDecoration Width="90%" />
also I can't get Thunder to work for this so using thunder is out at least for now until I get time to figure that out.
