This program was my life blood as the IT Director of a mixed environment. I am dieing painfully ever since I found out that this program does not work well with Leopard. It is painful to use with Leopard. I would not bother. PLEASE, PLEASE update this program. I'll gladly pay for it, or donate, or whatever. For what it does, it is completely unrivaled in the OS X world. It is, IMO an absolute essential for admins!
