FIX: ListBox control is slow to update the UI in a Silverlight for Windows Embedded application


Assume that you have a Silverlight for Windows Embedded (SWE) application that contains two ListBox controls on a Windows Embedded Compact 7 (WEC 7) device. When you run this application, there is about a one-second lag between when you taps on an new item in the bottom ListBox and the UI updating.


This issue occurs as a side effect of the design and implementation of the Silverlight for Windows Embedded runtime.
