Voiceover focus jumps to the top of the page

I find it very aggravating when I use a popup button in an iphone app to select a value and voiceover jumps to the top of the screen and I have to go back to where I was — sometimes very far down the page. It happens on popup buttons, tooltip info buttons, etc. How does everyone deal with this? Is it an Apple bug or are the app developers not doing something right?
