It's apparently an issue with the browser. I have had both of those problems, and contacted admin, they said they checked their site and it's not a problem with the site, but with the browser. Unfortunately I have those problems with most of the "main" browsers. I have issues with Firefox, Internet Explorer and Chrome. However, when I got a new computer with Windows 10 and the new Microsoft Edge browser, Edge does not have any of those problems so far. Every now and then I can get Chrome to work, but usually not.
