Hey there 
Ok this is so messed up! I have been working on this map for some time now.. and now when I try to move objects, they either don't move.. or when i finally get them to move , they don't stop moving! Only they move at a slow rate..  They keep going in the direction I moved them in. The only way I can get the object to stop moving is if i chase it down and click on it. 
This is getting so frustrating! I even tried making a new map, and the objects are doing the same thing.. It's Like the whole map editor has a bug or something. 
Does anyone know whats happening? 
No one seems to be familiar with this problem in the map making forum. 
cheers,
