Okay, so I have a completely new jar of Minecraft 1.5.1 and just out of the blue an inventory glitch happened When ever I try to click something nothing happens (In my inventory unless I hold down the mouse button. I don't know why and I don't think it's my mouse (I am going to switch mouse's but at the moment I don't think it's my mouse.) Any help would be nice, thanks!
EDIT: I have tried a different mouse, but it's still broken.
