I've just checked the source code for that page, Hans.
AB's server saw that the return key had been pressed 153 times in succession, resulting in all that white space. Perhaps you've got a sticky key on your keyboard?
Hi Buenchico......... The fact that AB's Server in The USA has recorded 153 presses on the return key, I am going to suggest as might President Trump.......'Fake News'.
It will be interesting to see if our Ed says anything on the matter.
