[BUG] Major SECURITY issue with Fast User Switching

I temporarly switched off all CPF components working under LUA in XP and after switching back to my Administrative account I was amazed to see that CPF is still off. A user with limited rights can disable firewall for the Administrator?! I wonder if it’s one of these $200 bugs matousec reported.

Comodo Firewall Pro RC3

The bug is reproducible with RC4 & clean WinXP install under VMWare. I wonder if this is or a security product or a TOY firewall if every kid working at my PC is able to completely disable protection.
