I'm attempting to add an Editor to an existing .NET 4.5 project. All of the other Telerik controls in the project seem fine so far - and RadEditor works at first, but is unable to change to either HTML or Preview mode.
When we click on either HTML or Preview, a File Not Found error is thrown. I've followed a few other threads related to RadEditor issues and have tried some proposed solutions, such as renaming the DialogHandler from .aspx to .axd, but nothing so far has worked. Right now, it appears everything in our web.config, references, etc. match what is in the Telerik Live Examples project.
Has anyone else encountered this problem, or any other ideas of what could be wrong?
