When I win a level, instead of letting me proceed to the next level, I get a white screen. If I lose, I can continue to play as long as I have a life. If I'm out of lives and try to accept lives sent by friends, I get the white screen again. I'm unable to play except by exiting the game and re-entering. If I have any lives sent by friends, I either have to accept all when I first enter or they are lost. I've tried different browsers - Chrome, Firefox, IE - and all show the same results, even after repeated clearing the cache and deleting cookies as well as making certain that each browser is current with all updates. I'm also unable to send lives to friends or to request lives be sent to me. The "Send" button does not work and the screen freezes. If I never hit "Send", I can exit from that popup and continue to play, but I am handicapped since I cannot send or request lives.
