Thanks but it's neither of those. This is specific to the site, not browser settings. I'm sitting in the middle of a drill now. As I pull the King over another square, there is a "stop sign symbol" so I can't release the mouse and move the K there. In fact, when I hover the mouse over the King without clicking, the status bar shows URL "https://www.google.com/intl/en/chrome/browser/". That's pretty clearly part of the site programming, unless there's a hijacking that perversely sends you to a Chrome page. Is anyone else familiar with this?
I am using Internet Explorer 11. After several moves in the drills, it will not permit me to continue. The literal link on moves shown by hovering is the link to upgrading to Chrome Browser. Any square that I click in the drill takes me to a Chrome or Firefox update page. This is frustrating. Obviously my browser is capable of doing the drills and playing games. (In fact, is there anything on the site that technically cannot function on Internet Explorer)
I detest Chrome. Since I prefer to use this browser, will I be unable to do the drills freely, or is there a way to defeat the nag? I know IE is a stupidly lame browser but for this activity I prefer it.
TIA for all of your time and generous efforts to help the community.
