Using two DLLs

I have a large program with several modules. Am trying to use both Richtextdesktop.dll and GDI+desktop.dll in the program, but B4pp shows "key already used" when I add the richtextbox desktop.dll. Is there a way around this?

I think that is because there is a FontDialog in both libraries. Try the attached version of RichtextDesktop that has had the FontDialog removed.
