So I've just installed FML and every time I load up a world or join a server my mouse spazz'es the **** out! My screen freezes and does weird things. I've even tried to play it without the mods in the mod folder but everything still acts up. Now playing in vanilla Minecraft is fine but whenever I download or install mod loader 1.7.2 or > the mouse just doesn't work.
