Hi,
before sending detailed data, please check, if this "message" has something meaningful for you:
****************************************
[Exception... "'Sys.ScriptLoadFailedException: Sys.ScriptLoadFailedException: Fehlender Aufruf von Sys.Application.notifyScriptLoaded().' when calling method: [nsIDOMEventListener::handleEvent]" nsresult: "0x8057001c (NS_ERROR_XPC_JS_THREW_JS_OBJECT)" location: "<unknown>" data: no]
Sys$CultureInfo$_getAbbrMonthIndex("")
******************************************
This happens, when invoking a dynamically created editor-instance in a Pane (and asp:panel) via Ajax from another Pane.
Without Ajax, all is ok.

Best regards,
Andreas

postscript:
this error happens only, when editor.enabled=false

Hi Andreas Kaech,
I have not seen this error until now. As I am not sure what scenario is, could you please send us a running project, demonstrating the problem?

Kind regards,
