Why isn't the "Open New Page" button working in Safari for iPad (iOS 4.3.5)?
Sorry for the delay in getting back: Updating to 5.0 didn't fix the issue, and I noticed the "dead spot" on other apps so, to I finally took the iPad to an apple store, where they diagnosed a problem with the screen: there was a strip, around 1 cm wide that was not working properly. Got a new one and now I'm a happy camper!!

EDIT: Typo fixing (I should use spell checking!)
