ok everytime im on safari i go to gametrailers to watch videos. the first time i watch a video, it works fine but then after that video is done and i try to go watch another video it doesnt work. its just a black screen and you can only hear the sound of the video. theres also no way to stop the video unless you press the home button...and i have to hold the home button until safari closes and reopen safari to watch another video...this also happens when i try to watch other videos on different websites. can someone tell me what is wrong? does this happen to anyone?
