We are using an older version of the Editor on an older ASP.NET application.  The version number on the RadControls/Editor/Scripts directory says 7_3_6.  I believe we determined that due to the older version of .NET that we are using, we cannot upgrade RadControls any further. 

 The behavior we are experiencing is that sometimes, when a use rclicks the Update button in the Editor dialogue, any HREFs in the editor window get changed from "path/to/file" or http://web.site/path/to/file to "about:path/to/file" or "about:path/to/this_application."  Has anybody else seen this behavior, or have any idea what causes it?  We can't reproduce it reliably and when it happens the only way to get it to stop is to restart the user's PC.

 Thanks.

Hi Matthew,

The version used is an old and it refers to the discontinued Classic Telerik controls for ASP.NET. These controls are not supported and also the .NET 2.0 is also not supported. 

Also, I am unable to define exactly why this happens. As you described, this happens inconsistently which does not lead me to a possible configuration-related reason for that behavior. 

However, I suggest you checking for any content filters related to Relative and Absolute URLs and see if disabling or enabling them would resolve the issue.
