I''ve got two classes at the moment: Object and ObjectManager Now I need to derive classes from Object but I''m having problems with that. Object has a virtual destructor and a virtal function Render (which does nothing at the moment). ObjectManager is a friend class of Object (and it''s derived classes). ObjectManager has a private member variable rootObject of the type Object*. The problem is that I''m getting an access violation when I call rootObject->Render() from the ObjectManager class. And I''ve made sure that rootObject points to a valid Object. Now here''s the strange part, when I remove the ''virtual'' keyword in front of the declaration of Render(), the problem goes away! I''d really appreciate it if anyone has even the slightest tip for how I might solve this. Thanks in advance.

Doh, nevermind. I fixed it already. It was due to some obscure bug in another file.
But thanks anyway. ;P
