Move to NPC when clicking

[PunkBuster]

My server has a few couple NPCs that do not open game windows when clicked. The best example of this is my Yggdrasil-giving NPC:

payon.gat,153,225,5 script Yggdrasil Berry::berry 4_F_FAIRYKID2,{

if (checkweight(607,1) == 0 ) end;
getitem 607,1;
end;

}


 It works fine. The problem is, when I click the NPC, the player character moves towards the NPC. Is there a way to make it so that the character will not move?

Edit: Shop NPCs are showing the same behavior.
