I’ve cancelled an OCR process on a 300-page PDF in DT about 10 minutes after it started, by clicking on the X icon in the Activity window. The progress bar disappeared but several minutes afterwards I noticed the iMac fan was still spinning and the DTOCRHelper process was at 100% CPU usage in Activity Monitor. There was no sign from the DT interface that the app was doing anything, so it seems that either the process was continuing (although cancelled) or that it wasn’t shut down properly. I’ve attached a sample of the process below, taken just before I killed it.
