Today we became aware of an issue in the recent weekly and live releases.
The problem only appears to have occurred when reading alerts from the Sites tree - as far as we aware the reports should have been generated correctly.
This seems to have affected passive scan results more than active scan ones.
We have fixed the issue and have re-released the weekly and live versions.
If you are using either of these releases we strongly recommend that you update them now.
Many thanks,
Simon
