Not Sure if this is the right section but im haveing problems with ctrl z

Im using blender 2.49b and i have re installed multiple times but when i do shift d to duplicate out side of edit mode and then ctrl z it take all of the items i did shift d with and puts them in the same coordinate so if i duplicate 3 times and do controll z it will put them all in the same spot after control z. any ideas on how i can fix?

  1. Check if you have autokey enabled.
  2. try using 2.56a

thank you, my problem is when i open i turn on record frames automaticly.
