Hi guys/girls,
Can somone please help - I have the latest version of Comodo Ice Dragon and my start page/ search page has changed to Yahoo Australia | News, email and search
(This is the Yahoo search page)
I want to use the page which was running before - comodo ice dragon (google search page)

Does anyone have the url and instructions on how to change this?
and has anyone else had this problem?

Thanks in advance for your assistance.
