Does it go away, or does is stay frozen like that? If it goes away I wouldn't worry about it. Same thing happens to mine. Also when I switch the camera orientation.
This will probably get ironed out in an OS update without notice.
It goes away normally but this time it hung up the browser, I find the browser a little quirky, how about you?
That would get frustrating if it locks up the browser. Yes it is a bit quirky at times but over all I am impressed with how it handles different sites. Remember that the OS is still very new. These kind of bugs will be removed in future updates. There is no need to return it for a Transformer.
I think a browser update would solve the problem, but only if we voice our problems. By the way, I know it's not defective. It is too awesome 99.9% of the time. I have an ipad and ipad2. I just love this little guy!
