So, this doesn't happen on servers anymore. But when I play with my friends on their worlds, the window will turn white, then light blue, then freeze. I deleted my account, added it back on, deleted resource packs, worlds, and changed the settings. I don't know what to do about it, please fix it soon. Also, with my little brothers minecraft, he downloaded and installed it on his android phone (version 4) and it will crash after the "Minecraft" logo shows up. won't even show the "Play/Settings/Achievements/Marketplace" screen. Please fix both of these soon.
