I think that has always been a problem with Cisco on our campus. I believe the last conversation I had with our SE about that said the 8.0 code had some improvements to client roaming addressing that. I just wouldn't trust using 8.0 code for another 6 months(my general wait time for bug fixes with Cisco)
