 Remarks 

 Processes issuing MouDeRegister calls must conform to the following 
 rules: 

 o The process that issued the MouRegister must release the session (by a 
   MouDeRegister) from the registered subsystem before another PID may 
   issue MouRegister. 

 o The process that issued the MouRegister is the only process that may 
   issue MouDeRegister against the currently registered subsystem. 

 o After the owning process has released the subsystem with a 
   MouDeRegister, any other process in the session may issue a MouRegister 
   and therefore modify the mouse support for the entire session.
