I have a UIWebview that I load with loadHtmlString. The html has some links in it, and when they are touched I intercept that and do another loadHtmlString. This all works fine except that the gray box, (the tap highlight), remains on the screen after my next loadHtmlString call. Why is this happening? What do I need to do to cle...

Probably easiest to explain by example: In the Facebook 3.0 app, if you click on a friend, it shows "Wall | Info | Photos" in a UISegmentedControl, which acts like a UITabViewController. If you then click on, say, a photo, it pushes a sub view onto the UINavigationController stack, which slides the UISegmentedControl (and parent view) t...
