I know the storm screen is supposed to be loose and move slightly from side to side and up and down, but I think mine is too loose. Is there any way to tighten this up or am I stuck?
There isn't any adjustment in the screen fit. The screen just free floats inside the frame. That said, apparently some of the clear protection films available wrap around the bezel edge and that takes up a little space, removing some of the play in the screen.
