invalidate(Rect) from onTouchEvent causes one extra invalidate()

Question

Hi,

I have this strange problem. I use a View. When I first run the program it shows the View correctly. Then if I 'invalidate(Rect)' a part of the screen when 'onTouchEvent' is clicked it invalidates all the screen and not only the rect I asked for. This happens only when I initially start my app and only one time. After that first time it works flawlessly. Also this is done only from 'onTouchEvent' and not from 'onKeyDown'.

I'm I missing something? Is this a bug?
