I write all before and I posted a lot of images
I add that I am testing the same in a NEW PC because someone here muy simply said that it happened because of my pc, but I said him that with ALL other browsers it DOESN'T HAPPEN !
SO, In this NEW PC (bought 2 months ago) with another operating system (windows 8.1 updated and installed yesterday in the pc formatted !!!!) I have installed Maxthon in a clean installation .... IT HAPPENS THE SAME: Disappear the website, disappear the windows bar as a conflict with the RAM or with the CPU.
It IS definitively A MAXTHON BUG
