I am making several modifications in application definitions with live display enabled, and after saving the configuration occasionally to keep changes, the following error message appeared (Win 10, 64 bit): "Out of resources ...". After pressing Ok button in the error window a strange behavior occurs with the scanner. For me the only possible way out is to close the program and start scanning again, losing already scanned data.
Something I did realize different from other occasions with the same error message was the enormous stopping threads number not equivalent to existing connections: 7209033 threads left
