[This note has been sent to the following InterNet address(es): [log in to unmask]] I will happily add my name to a list inviting HP to explain the recently-announced security problem. I need to be able to assess ,on a well-informed basis, whether I should worry about this issue. I have upwards of 700 users spread across 4x 992/400 systems under MPE/iX 4.0 , so migrating to 5.0 is *not* an easy option. Tony Rendell [log in to unmask]
