Feedback: Problem with latest Firewall update

I have been using the Comodo firewall Version: 2.3.6.8.1 for some time and have found it excellent. However the recent update has given me some problems. I use XP-Pro and upon start-up when XP is almost fully loaded there is now a considerable delay before it is completely loaded and sometimes it does not finnish and freezes up the whole system. I run 6 XP-pro systems and I have had the same problem on the 3 that I use on a daily basis. I have now gone back to the older version and have had no further problems.
