Hi Colin,
Can you reproduce this issue with our online demos: http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx?
Also, are you using the latest version of the controls (Q2 2015 at the time of writing)? If not, could you try upgrading to see if this will resolve your issue?
Other ideas I can offer are:
- consider using RadWindow. You can load an entire page with the editor on it inside the RadWindow. This will provide a separate context to the editor and it will minimize interference from other code on the main page
- you can also use the ContentTemplate of the RadWIndow to remove other popup code in case it is causing the issue. In this situation, however, a few lines of script are needed: http://docs.telerik.com/devtools/aspnet-ajax/controls/window/troubleshooting/radeditor-does-not-work-in-radwindow.
If neither helps, can you post here a simple snippet that shows the problem?

One thing we are doing different than in any of the demos is that we are using a Tools File .
I have updated the tools to the latest version and we still get the same result.
Here are the settings we have for the control.
<telerik:RadEditor ID="rdeNoteDetailEdit" runat="server" Width="99%" Height="250px"
EditModes="Design" StripFormattingOptions="AllExceptNewLines"
ToolsFile="~\App_Data\BasicTools.xml"
SpellCheckSettings-AllowAddCustom="true" BorderWidth="1px"
BorderColor="#A6A7AB" OnPreRender="rdeNoteDetailEdit_PreRender"
Content='<%# Bind("NoteDetail") %>'>
</telerik:RadEditor>
ToolsFile="~\APP_Data\BasicTools.xml"
...
<root>
<tools name="MainToolbar" dockable="true" enabled="true">
<tool name="Cut" />
<tool name="Copy" />
<tool name="Paste" shortcut="CTRL+!"/>
<tool name="Undo" />
<tool name="Redo" />
<tool name="AjaxSpellCheck"/>
</tools>
</root>

I tried implementing the changes suggested, and the problem still exists.
Where the code throws an exception is within the MicrosoftAjax.js file within Telerik.Web.UI.WebResource.axd
Is it possible there was something updated or not updated in your version of the MicrosoftAjax.js file?
The exception is thrown once the spell check is complete.
I tried to recreate the same scenario by creating a sample ASP.NET page, but to no avail. I suggest examining the attached sample, and modify it to the point where the same is reproducible. Achieveing that and providing back the project, will enable us to investigate and determine what might be the problem.
On a side note, the MicrosoftAjax.js resource is not delivered by Telerik assemblies, but from the native ASP.NET ones.
