50% of the class libraries are the framework, but the main reason for the other 50% is the fact that one of the forms contains a 10-page pageframe, and each page drops down to more screens, created as Containers, which are added programmatically when needed!, and that does cause a bit of complexity - personnaly I can't stand having to write the sofware this way, but it's how the users wanted it to look, oh well...
