I've been getting back into the Windows 10 Edition of Minecraft, but the fun I have is hampered by random crashes while playing in Survival. It only occurs while trying to break blocks, and when it happens, everything freezes, neither the keyboard nor the mouse can do anything, and after a few seconds the Minecraft window closes and I have to reopen it. Sometimes it puts me back to where I last saved, but other times it puts me a little bit before the crash, presumably where it had autosaved. The last time it happened, I was trying to cut down a spruce tree that had just grown from four saplings. When I reopened Minecraft, the tree wasn't grown, as its saplings were still there, but half of its leaves from before the crash were still there, just hanging in mid-air.
