Weird Avie movement

For some time now I log in and then my avie is constantly moving slightly forward on it's own. If i pan around witht he cam, it gets reset to default view. I can't even right click on things to sit, view, edit without the cam moving back. This is very annoying and find it very hard to do anything in the game. On occasion i don't get this at all. I don't know if it's a setting within the game, a game glitch, or a setting with my graphics card. I have a high end Nvidia card and do have settings in the game to get used of the quality graphics i can get. Please Help!!! Anyone have this problem?

I'm having the same thing happen.....or I appear at 10,10,10.

I can rotate in a circle, but I can't move with the forward and back arrows.

All sorts of weird stuff is happening today....the stuff just isn't loading properly.

Another family member has a game joystick hooked up to this computer. When the computer boots up, it's defaulted to be on. So the joystick is not always in true center causing my avie to keep creeping slowly. So there's buttons on the joystick to turn the joystick off. Hence, solved my annoying little problem.
