Defense+ freezes target app for too long!

Ok, so I’m not sure if this is really a bug, more of an annoyance that should be fixed.
It seems that the freeze that occurs on an unknown application has been steadily increasing over the last few months. (I’m not sure if this has anything to do with updating to latest versions)

For example: At the moment, when I install a program, the defense+ will popup, and i will click on ‘treat as installer/updater’ and change to installation mode. But the freeze that follows is just too long - about 1 minute, whereas back in the good old days it was only about 5-10 secs for me.
This makes installing/updating/allowing apps access to stuff a real pain.

Is this length of time normal?
I’m running Vista x64. Comodo firewall version: 3.13.126709.581


Just updated to 3.14, and D+ seems to be zipping along nicely now,
even though it’s forgotten all my settings. 88)
