Why comodo 2.4 not log till when i log in with username and password?

Hi to all i have a question about last version of comodo firewall 2.4
I have installed on xp sp2 and i had notice that during a period (about 30 minutes) that my pc stay on screen of log in the log screen of comodo don’t report nothing(i controlled after log in) and after i log in with my user name and password in the same screen appeared more logs of packet denied.
Is my pc protect before log in with user name and password? is a “normal” problem of comodo log system that not start and not register till when the process cmdagent.exe start?

Thanks to all
