For no reason in particular, I decided to block an arbitrary netrange with Comodo (e.g., 83.138.0.0 - 83.138.255.255). Worked perfectly while logged in as ‘Admin’.
Logged out (no ‘fast user switching’) as Admin and in as a ‘Restricted/Limited User’. I was able to access the blocked netrange with no problem and no warning.
Is this peculiar to my configuration or is my install of the latest beta ■■■■■’ed? 
WinXP Pro SP2, Firefox 1.5.0.6

User account should not matter. How did you block?
I created a rule in ‘network monitor’. Blocked IP in/out to “any” in netrange x.x.x.x, and then moved it above all ‘allow’ rules.
Nevermind. No problems here.
Possible explanation for the (non) problem. I installed two extensions to Firefox plus installed Ewido Antimalware but did not reboot after installation.
I just rebooted and I don’t have a problem with Comodo anymore. Sorry for wasting any and everyone’s time.
