I am on P.C. and have been playing Minecraft recently. I play on the ihascupquake oasis mod and for some reason when I tried to right click the chat bar came up in the bottom of my screen so I pressed enter and it went away. I pressed another several times and the same thing happened (The chat bar came up when right clicked.). In that time I couldn't break blocks as you can't do anything when chat bar is up. I went into chat settings and selected "Chat bar: Hidden" and the chat bar went away but I still couldn't break blocks. I left the game and came back several times - no change. Can someone please help me?
