Getting rid of orangeworld.co.uk as default home page

[Guest GabbaGabbaHey]

My TG01 is unlocked and I am using an O2 SIM in it.

Whenever I use the righthand - "Browser" - soft key, it invokes Opera, but it tries to go to orangeworld.co.uk, and I then get an error message saying that I need to be on the Orange network to access this page.

I have looked through all the Opera setting (in opera:config) and have done a search through my registry for the string "orangeworld", but cannot find any mention of it. I'm running Opera Mobile V10.00.

Does anybody know how I can stop Opera from trying to open this page?
