Bugged Movement Upon Logging In

Occasionally when I log in my character is spinning, strafing, moving in either direction, or any combination of those three. Also I am unable to log out because I am moving, usually have to tab out and force a shut down. I do not press any buttons and this happens. Sometimes I am lucky and am able to get my character to move correctly again. I received some help in the forums but the success rate is probably below 25%. Logging back in does nothing. Closing the entire client does not most of the time. I think it is either a bug or some weird problem with lag.
