If it walks like a DUCK....

Shoot it.... Ok at least turn it off.

Is your drawing so jumpy that you cant draw or do anything? I'm sure you've already checked to make sure that snap and grid are turned off. If its still jumpy make sure you have turned off the DUCS (Dynamic UCS). there is a button for it on the bottom of your Autodesk screen right between OTRACK and DYN.
