The obvious solution would be to make the close button touch the top and
left borders of the screen. This way, you can just throw your mouse up-left
and click without aiming, as per Fitt's law.

A bug was reported ~9 months ago or so, but apparently there were bigger
fish to fry first - so the close button is offset by (x,y) =  (2,1) pixels
making it very hard to click.
