Change default web browser?

[chrysalis]

I have the same problem too. I delete Opera 9.7, then IE became the default rather than Opera 9.5. I read the previous posts that I need to go to "preference" to set Opera 9.5 as default, but I don't see such option in either Opera 9.5 or Opera Mini 5 under the "setting" option.

In addition, I find Imagio's zoom bar won't work for Opera 9.7 or Opera Mini.

Anybody offer a hand to these two problems? I would be greatly appreciate it.
