My default browser is Google Chrome. Over half of the time when I try to start any of these games, the background screen comes up but the big orange box with King never comes up. It fails to load. I am forced to go to Internet Explorer to get any of the games to start. I dislike IE for lots of reasons, but it always starts the games just fine.
I am running Windows 7 home edition premium on my computer if that make any difference. I will not be switching to Windows 10.
