I decided to play Minecraft after school, but I noticed that when I clicked on it (it was on my dock) a question mark would appear on top of the block-of-grass logo. I had my brother mess around with some Minecraft files to try to fix it, but he couldnt get anything. He tried removing it from the dock and putting it back on again. Our only issue is that we don't know how to get it back on the dock. We have multiple Minecraft files that my brother has downloaded in the past and we don't know which one is the original Minecraft file. Someone please help. We don't know how to play without it being on our dock or desktop. If that, if anyone knows why the question mark was there in the first place, please speak up.
