Comodo Firewall unresponsive when alerts pop up


I’ve been happily using Comodo Firewall v. for a couple of months and everything was working brilliantly until now. When I get an alert, Comodo just doesn’t seem to react to allowing or denying the application. No response at all. It seems to close on its own after 15 seconds or so. And of course, it keeps bringing up the same alert again and again. Ideas?

If I download a more current version (assuming it’s available), is there a way to transfer settings?
