[ROOT] passing classes to functions

Dear Rooters,

I build such an organized  root macro Pippo.C:
(I give a simplified sketch only!)
____________________________________
#includefiles

void Func(MyClass* aa){
.....
}

void Pippo(){
MyClass* a = new MyClass(...);
...
function(a);
...
}
_____________________

Note that:
-Isnide the body of macro Pippo I call the function func
-a is a pointer to class MyClass object

My problem is:
IF I use the class MyClass including it directly by the INCLUDEFILES at
the beginning of the script (i.e. #include "MyClass.h") it works,

If I include MyClass via libMyClass.so
(i.e.   I put at the beginning of the Pippo macro the command  
	gSystem->Load("libMyClass.so");
 )
it DOESN'T work!

Why this different behaviour? 

Which are the advantages in using a compiled library (with a Root
Dictionary) with respect of using a normal include file.h?

Thank you, Tommaso


P.S. 
I know that may be using functions would sound like "a la
fortran77"... better is implementing a Class, isn't it?
