Game Mechanics: Shift+up key bugs out with auto run random

[Rangerboy]

I will post more information on this thread once I figure out how this exactly happens. On my set up I have the numlock key as my auto-run key. While I was on auto-run and messaging using shift-up to get previous message, the game seems to have the shift key stuck. This being said, if i hit up it acts like the shift key is down still and gets previous messages. I've tried re-hitting the shift key, hitting enter, ALT-Entering the screen and maximizing it again. The only way out seems to be to camp out. This doesn't happen all the time, but seems to happen when certain button mashing takes place.
