Yeah everything you both described is because of Internet Explorer. IE is not so good anymore, even Microsoft ditched it to develop another browser. Try Microsoft Edge, Chrome, Firefox, Opera. Any of those will be fine.
I was using Firefox on the old stuck-in-the-corner work computer where I sit on lunch to do my gameliving and whatnot. That worked fine for a long time - up until whenever I started posting here about it - but I basically get the message. See about getting Chrome on there.
