I've been using Dolphin broswer since pretty much when I got my phone. Someone posted a poll about which browser was people's favorite. After some good feedback on the stock browser I thought I'd give it a try for a while (especially since it has pinch zoom-out now). However, I can't do crap with it without it opening the dolphin browser.
For example, home page is google. I search "droid forums" and hit the search button and Dolphin opens up and heads to the results. I punch in marincarservice.com and it goes there, but click one of the page links there, and it opens Dolphin.
I've turned off the default option in Dolphin.
