Mistery solved...it is a Flash player bug # 2267790 . It has to do with removing a TextField (Flash Player component) from the stage while it is focused. The fixes above are a partial fix, but it requires a change to Flash Player in order to completely resolve the issue. This bug is open, and listed as a high priority but hasn't yet been scheduled.
