No need to lock the object, just the drawing surface.  I use 
Lock()/UnLock() around the pick method which works fine.  Pass a 
refrerence to your renderWindow into your mouse listener, then call 
_window.Lock()/UnLock().  If your mouse listener is in a different 
package, then provide public wrappers for the Lock/Unlock methods.  Hope 
this is clear,
