You should instanciate it with:

   hComboBox = NEW ComboBox(Frame1) as "mycmbbox"

(note the "as xxxxx"). Then declare:

   public sub mycmbbox_change()
   .....

The toolbox works because it does automatically something similar. Ask 
Benoit, he knows better than me: the interpreter does know nothing about 
variable names, so if you rely on variable names to manage events, you fail.
