Anytime I am linked to a YouTube video from a forum, it opens a second window which i am assuming is the youtube app. When the video finishes playing, I can not figure out how to close the App. If I double click the home button, I can get back to safari but all I see is blank white pages. If i double click the home button again and close YouTube and safari, all will work fine again. There has to be something I am missing. This iPad 2 is my first experience with an apple product. All help is appreciated. Thank you.
