Twitter timeline: why does it the scroll to top each time I return to it from a tweet?

I'm using the Twitter app and also the Tweetings app. When I view a tweet in the middle of the timeline and click "back" or "done" to return to the timeline, it scrolls to the top and I lose my place in the middle of the timeline. Very annoying. What am I doing wrong folks? Is there any way to make sure that when you go back to the timeline you're not automatically moved to the top?
