Hi,

I am trying to load the AppStylist from the application to do the runtime editing. There seems to be a problem with UltraToolbarManager being present on the form.

Following is the exception trace. Any clue for the error.

System.NullReferenceException was unhandled
Message="Object reference not set to an instance of an object."
