Beat,

When working with behaviors and engine events I usually define a  
second command in the behavior script that the behavior calls from the  
engine event. For example, a mouseUp would look like the following:

===============
Behavior Script
===============

on mouseUp pBtnNum
     _mouseUp pBtnNum
end mouseUp


command _mouseUp pBtnNum
     DoA
end _mouseUp


Now if you want to add additional functionality in mouseUp then you  
can make a call to the behavior _mouseUp handler. This will provide  
all of the functionality that the behavior provides at which point you  
can provide any additional functionality. In your case you would call  
DoB:

===============
Control Script
===============

on mouseUp pBtnNum
     _mouseUp pBtnNum
     DoB
end mouseUp
