Comodo Dragon does not work on school network

I have installed comodo dragon on my new ASUS U31SD. When I connect to my school’s network, which is unsecured, but requires entering login information on a page before allowing internet access; I cannot access any pages. I get error 137 before logging in (it does not redirect me to the login page), and after logging in with another browser, I still cannot access any pages.

Did you install Comodo Dragon with Comodo Secure DNS? I can see your school network blocking the use of third party DNS servers, as it would most likely bypass there website blocking software. To disable Comodo Secure DNS in Dragon go to settings (dragon://chrome/settings/) click on “Show advanced settings…” Under Privacy you will see “Enable malware domain filtering (Comodo Secure DNS)” Disable it.
