So here's the problem. Sometimes I'll be breaking blocks, like a birch log, when this most recently happened, and the game will freeze. I wait for a moment, and it goes to a completely white screen. After waiting here a moment, I close the window. When I try to open my web browser or re-open Minecraft, it doesn't work. I can't even open the Start menu, whether I click the icon or press the windows menu shortcut key on my keyboard. I can't open Task Manager, or any other Ctrl+Alt+Delete function, and I need to restart my computer (Hold the power button down, you know how it is) to get anything to work. The parts of this that happen after Minecraft closes could be unrelated, but I doubt it. If this could be fixed, that would be great. I understand that the developers and bug fixers must be very busy, and I don't know if this has happened to anyone else because nothing appeared when I searched for this issue, but if/when you get around to it, I'll be greatful.
