comodo 327 beta’ s BUG?

Hi
I am using 327beta now and found a strange problem.
I creat a new predefined policy named “network application” in D+. Block all network app creat executable files.
than I download a exe file by browser found the policy is working and the exe file can’t download and comodo logged this event. however, I found that D+ can’t block the exe file download by flashget even if the log indicate the download action be blocked.
so my question is this is a bug or my policy problem?
waiting reply

thank you
