Any program that requires you to authenticate in the browser. Touitier, TripIt, you name it. It's a known issue. As is the fact that you can't see any password characters. Not to mention I think the location of the refresh button is crap. That's a personal thing though not an actual problem with the app - I just can't count how many times I've hit the home button or another link while trying to swipe down that little menu bar. I can't stand that...but that's just a personal preference, not an actual programming flaw like the others. And the password isn't controllable either, it's a problem with Google code or something.
I spent three days thinking my TripIt app was broken because it wouldn't authenticate. I uninstalled xScope and it immediately worked in the regular Browser.
Another thing that doesn't work, for example, is posting a comment to my blog. Look in my signature, go to my blog, and try to post a comment from xScope. You can't. But it works perfect with the regular browser.
Anything that requires a redirect rarely works. Etc etc.
The browser is great on the surface but it has too many minor issues for me to keep it installed. I paid for it, but for me, it's garbage. It may work amazing for some people though. Depends what you use it for.
Go install Touitier and tell it to authorize...then when it tries to redirect back to the app it will tell you page not found. Do it with the stock browser, works immediately.
I actually planned on blogging about this very issue tomorrow...comparing Dolphin, etc.
