Hello Olivier. This definitely shouldn\'t be happening. So if a scan does hang, the Stop button in NEWT doesn\'t help?
Could you try disabling \"IP Address (Internet IP)\" under Scan Properties and see if it helps? You can also scroll down or sort the \"Scan Status\" tab during a scan and see which machines it seems to be stalled on. That may help us determine the issue, or at least where it\'s happening. Rarely does a stall occur, but if it does, it\'s usually a few machines.
If you can get the hang to happen again, sending us a screenshot of NEWT may help as well.
You are using version 2.5.154, correct?
