Here are some ideas: Have you restarted your computer -- if not do so and see if that fixes the copy/paste stuff.
You did not say which version of Window or Internet Explorer you are using, but it sounds like IE 9. To turn on the bars across the top, open IE and look at the far right. There should be a faint box with three dots. If you right click on that box you will see a list of "bars" that you turn on -- see which ones you like (I have them all turned on).
Hope this helps.
