glGenLists returns 0 when you pass a negative range or you are using it between glBegin() and glEnd (). In another case it must works properly.

Also make sure you create the window before calling glGenLists. This may be a problem if the call is in a constructor.

An renderContext is bound to one thread… you should do all opengl stuff in the same thread that created the RC.
