"right click a blank spot just below the blue title bar"
Title bar runs across the top of the screen (usually blue). In a blank (unused) area below this, see if there are any options that want checking to restore any missing toolbars that you want to make permanent.
Before you do that, just hit the F11 key and see if that temporarily helps. If it makes things worse just hit it again.
Yes - from Internet Explorer, as I said in #2.
There are some unanswered questions.
Always pop back and let us know the outcome - thanks
