Here is the solution which was posted in this thread.

This is for the .net assembly 2_6_3. I based it on the help file http://dev.fckeditor.net/attachment/tic … 2115.patch

Steps:

Open the FredCK.FCKeditorV2.vs2005.csproj in Visual Studio 2005

Open the file FileBrowser > FileWorkerBase.cs

Go to line 119

Replace:

Response.Write( @"(function(){var d=document.domain;while (true){try{var A=window.top.opener.document.domain;break;}catch(e) {};d=d.replace(/.*?(?:\.|$)/,'');if (d.length==0) break;try{document.domain=d;}catch (e){break;}}})();" );

Replace with:

Response.Write(@"(function(){var d=document.domain;while (true){try{var A=window.parent.OnUploadCompleted;break;}catch(e) {};d=d.replace(/.*?(?:\.|$)/,'');if (d.length==0) break;try{document.domain=d;}catch (e){break;}}})();");

Compile the project and then reference the new dll file in your project.

I hope it helps .
