Voiceover Jumps Back to Beginning of List after Reading a Post

In a lot of iPhone apps, if I am reading through a list of entries and then click on one to read the details, when I hit Back to go back to the list, I am placed all the way back at the beginning of the list. Is there some setting I'm not aware of that can remedy this. Examples of apps where this happens include Facebook, Voicebook, e-mail--seems to me it hasn't always been this way. It's very time-consuming and frustrating.
