Hi Guys,
depending on the used browser (IE, FF, Chrome) we sometimes run into a "NullReferenceException" while trying to open a picture to edit. FF & Chrome working almost all time while IE throws an exeption one of 3 times.
Within this forum we found the guess that someting with webResources/seasson state server is the reason of this error (http://www.telerik.com/community/forums/aspnet-ajax/editor/editor-image-manager-refresh-image-save-image-doesn-t-work-very-well.aspx#2187725) - but we can exclude this after a few tests.
This is the exception we run into:

After a few investigations we can confirm, that the error does not happen if we run our web application in only one working process (application pool). Normaly four are default. Now - do you know something about problems with the "ImageEditor" and IIS application pool Working processes? This this a known Bug? I've tried the newest Telerik DLL (Q3 2012) but this does not help anything. Best regards, Felix2012.11.20 17:44:30.988 ThreadId=7 Fatal ErrorsHttpModule
