How do disable Opera as default browser

[noreboy]

So I downloaded Opera 9.5 the other day. Works alright, not the best things in the world, but it has it's pros. Anyway, when ever I select on a url link or view picture mail, Opera is launch instead of IE. I want to keep Opera on my phone, but want IE as my default browser. Opera doesn't work with the old pic mail plugin, nor does it work with TCPMP. How do I disable Opera as the default browser without doing any reg edits?

off topic, but anybody know how to make the on-screen keyboard stop popping up when entering a url in Opera?
