Not being able to arrow back to the previous pages
I have a Mac OSX 10.8.2. I am not a computer geek, so bare with me. When I want to do a search for something, I click the Safari icon for my home page,
I type in a search topic in the box, then a page comes up with my search results. After opening a topic in my search results and I am done reading it, most generally I cannot go to the two arrows in the upper left hand corner of my screen and arrow back to the page that has my search results, the arrow isn't highlighted. The only thing I can do then is click on the X in the upper left hand corner, which eliminates everything and I have to start all over again from the beginning. When I am searching for something, unless I use the same wording as I did in the previous search, it usually comes up with different items on the search results page. Remembering the exact wording I used previously is a challenge, sometimes at my age. Also, with this arrow not highlighting, if I go into one of the items in the search results page and it gives me some links, (I guess that is the correct terminalology), to click on that may answer my questions, I can't back out of the one link to click on another one, because of the arrow is not being highlighted.
Is there a setting in the computer that I can change so the arrow with highlight every time? This doesn't happen in all cases, but it does in most. I really get aggrevated having to retype search topics over and over again.
Thanks for the help and please keep the answer simple, like I say, I am not a computer geek.
Thanks.
