Right on this same page is another thread with this very same topic. Did you even take a millisecond to look down on the page before making this post?
I'm usually not the type to post a reply telling an OP to do a search but in this case, you don't even need a search which is why it amazes me to see a thread with this topic. It's right on the first page, not that far down.
Hope it helps. if not, a search should. This topic has been discussed over and over and over and over and over and over again.
