If I remember, window move and resize return those events only when you stop the resizing movement (ie mouse comes to a rest) or you let go of the button.
I also recall that on a slower computer the o/s doesn't give enough remaining cpu time to the app for it to update the game very often while draggin the window, so it may appear to not be updating at all when it's really down to not enough cpu time to share. I found that on a faster computer the display actually would update while dragging.
