Having read through the post it does look like you have a problem. Here are some things you must try if you havent already: Try a different browser. If you're on Firefox, try Chrome, and vice-versa. Try in an incognito window (CTRL+SHIFT+P if on firefox, It might be CTRL+SHIFT+N on chrome). Create a new user profile in your browser, and try again. (Methods vary between firefox and chrome, and can be complex). It sounds like you might have a browser extension causing problems, or some other kind of browser bug - sone ore more of these should fix that. I cannot emphasise enough: the problem you are having is not normal, and something is creating that problem.
