Agnitum Outpost Pro & Prevx1

I run Prevx1 concurrently with Webroot Spy Sweeper to complement the primarily signature based antimalware program with a primarily heueristic based antimalware program. In studying firewalls I've read about conflicts with Prevx1 when its algorhythms run at cross-purposes with those in the firewall. Comodo is the firewall usually mentioned.

Has anyone heard of problems using Outpost Pro with Prevx1?

Thanks,
