Thank you.
Ok thanks for the info!

Unfortunately I ran in another thing you might want to fix.
Using StiWpfDesignerControl on a Window I get "System.NullReferenceException: Object reference not set to an instance to an object" when trying to move the following vertical splitter:

This is the corresponding Stacktrace:

This does NOT happen if I call the Editor via DesignWithWpf only if I use StiWpfDesignerControl on a window.
I hope you can find and fix this too...
Thanks and cheers,
