For the past several months the browser back key sometimes works and sometimes doesn't... I have to right-click on the left arrow and scroll to the page I want. There doesn't seem to be rhyme or reason and it happens randomly, no specific website...

I don't know. I see this a few times here and there. Sometimes the 'Back Arrow' is faded and doesn't show at all where I just was. If needed, I'll click on History to view the 'Recent History' drop-down box to find what I need.
