I've been using AutoCAD 2008 for a couple of months, and a couple of weeks ago I started experiencing some problems with my cursor.  Whenever I zoom into my drawing, my cursor starts getting slow and jumpy.  It is really frustrating and I don't know what to do to fix it.  Can anyone help?

Try to change the acceleration or other graphics card settings. If there is any disk activity you may need more memory (RAM).

Thanks for the reply.  I ended up turning off the grid and object snap.  That seemed to fix the problem for now.  Thanks!
