Bug with chest-minecarts

Yesterday, I was playing Minecraft and I tried to open a chest in a minecart, first, it didn't allow me to open it, and secondly, I wasn't able to open neither my menu (where you can see your personal storage) nor other chests. My first reaction was closing the game and it worked until I needed to open a chest in a minecart, I tried this solution 4 times. My second solution was closing the program, and again, it worked until I had to open a chest in a minecart.
