In my case "...has been modified externally, overwrite?" shows periodically equal to autosave period. It makes autosave function useless as it should save projects without any message. When i live SoapUI for a long time i gave stack of many mesages to click. This is so frustrating, as i head to disable autosave and already lost some work because of that.
