That has nothing to do with object pascal, but all with the one who 
designed the classes you're using. IMO calling virtuals in yuor 
constructor/destructor isn't a bad thing if you know what you're doing. If 
things has to be called in a certain order, that is nothing different than 
programming other routines.
