I have World of Minecraft for Windows7, and Linux (ubuntu), On Windows, World of Minecraft works FINE completely normal. On Linux, I can't spin while moving, and I can't place or destroy a block because left and right click are the start menu apparently. I don't know what is wrong, or if it's just Ubuntu, it's a Linux based OS though. I also don't like the weird colors with the new updates with World of Minecraft, it messed them up. I like to build and I can't do that without placing blocks.

Please help,
