When you are in http://www.personalfirewall.comodo.com/ and use IE7 Rc1, and hover over “products” top left, the drop down menu goes behind the “Download Comodo Firewall For Free Now”.
AOWL: Tx. We’re not officially supporting IE7 until it’s released, but we’ll have a look anyway.
Ok, it’s nice to have it working when it’s released… 
I know that it’s a PITA to get it to look and behave similar in IE6, IE7, FF and Opera…
Good luck! ;D
