llTargetOmega problem.

Ok this code:

  default
  {
     state_entry()
     {
  	   llTargetOmega(<0,0,1>,(PI/8),1.0);
     }
  
  }

was in an old script (Hiro's Holo vendor HOLO boxes), when I rez anything old with this code in it, I can't edit the size/rotation/position boxes in the edit window.

Reset/recompile does not fix it, but if I set the script to not-running it's editable, or if I remark this line out.

When I drop this script into a new prim, I don't have that problem.

Any ideas why this is happening?

Thanks.
