Why can't they tell the screen to go completely white and then refill. This would allow people to know when the page was reset but not be as distracting as the full black that you see when it refreshes. It is much better on the K3 than any of the other previous versions due to the speedy refresh rate and I hardly notice it after a while but it was a little had to get used to for new users.
Relating to refresh... I noticed a lot of ghosting when using the web browser. It's like it was not completely refreshing. It will go away if I manually refresh. Sounds like a software issue.
