Movement and Skill controls somehow change!

Yeah, sometimes when I'm playing either in town or a mission (PvP included) my mouse does not move me by point and click, I can't use my skills by using the 1-8 keys, and my spacebar does not let me attack or talk to an NPC. I think it's something I press because after mashing my keyboard for awhile it fixes it self, but it's really annoying when it happens during PvP. Please halp me.

It's your keyboard, or mouse. Make sure they are connected, f00.

They are connected, the mouse can still target people but it does not let me move by mouse. I have to use the wasd keys to move, but use the mouse to click my skills. I can still move the mouse around and type messages, but it's the control scheme that is messed up.
