Cannot see all classes from referenced Com-Visible DLL

Last Modified: 2016-02-11
I have a DLL VB.net application written in Visual Studio 2015 RC.  It's Com-visible and I checked "Register for COM interop".  The name of the dll file (I believe this is called the "assembly name"?), the project name, and the root namespace name are all "AltekVB".  I copied AltekVB.tlb from the Debug folder to the system32 folder and referenced it in an Access 2003 .mdb database.  Why would only some of the classes defined in AltekVB.dll be recognized (come up in intellisense) from VBA?
