RadAjaxLoadingPanel In MasterPage - Error

Hi,

I'm having an issue... But I don't know why / where... Can you help me?

I think that I've isolated the problem.
In my Page I have:

<telerik:RadAjaxManager ID="RAMP" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RG">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RG" LoadingPanelID="LP" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

If I put my

<telerik:RadAjaxLoadingPanel ID="LP" runat="server" ZIndex="100000001" />

in the same page, it's working well.
If I put this same code in the master page of the page then the ajax calls are not working...

When my RadAjaxLoadingPanel is in the masterpage, in the console I have this:
POST... 500 (Internal Server Error) ... Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=RSM_TSM

Can you help me please?

The RadEditor on screen Character Count doesn't match the character count when accessing RadEditor1.Text.Length on a postback. How can I access the count that is displayed to the user as they are entering text?

Below is an example:

Screen shows 21 characters, but when doing RadEditor1.Text the result is :"0123456789 \n0123456789"
This has a .Length of 22 characters.
