Unwanted Android selection behaviour... different in Flex versus pure ActionScript... Why?

Hi,

I'm trying to get to the bottom of the text selection behaviour on my Android Xoom under different circumstances:

1. In a pure ActionScript mobile app, selection and copy / paste is controlled through a floating control that appears on screen without resizing or otherwise moving anything

2. In a Flex mobile app, selection and copy / paste is controlled through a UI bar that appears at the top of the screen, pushing the entire app downwards, losing focus on my textfield, ballsing up every bit of control I have in addition to confusing the hell out of my user whose finger is no longer pointing at the piece of text they wanted to select but rather at something else that is about a half-inch above that point...

So...

Obviously, I want to get to 1. for Flex - eg: I want to allow selection and copy / paste without loss of focus, without repositioning and without confusing the hell out of my user.

Does anybody have any clues how I can achieve this?

Thanks,

G
