Hello, how come I can't break blocks with my bare hands? I can only break blocks with items or blocks. Heeeeelp. D: Other users don't have this problem, just me.
Hmm, that's weird. Try deleting you your minecraft.jar and see if that does anything? I've never heard of that issue.
Hmm, if it's just you that has this problem delete your profile in the world folder. Keep in mine you will lose everything in your inventory and your home so make sure you write down the coords or set a warp and place your items in a chest.
