RESOLVED: Project reference to .vbp not working

I have PROJECT,vbp that references PROJECTX.dll. I want to load both projects in the IDE and have the 1st project ref PROJECTX.vbp rather than the .dll.

I've done this before, but I'm in a situation that if I compile, it tells me the class objects I'm creating from the PROJECTX library are UDTs which they're not. I find that I don't have intellisense on any of PROJECTX's classes, however I have PROJECTX in the intellisense list when I DIM a var.

For example, in PROJECTX, there is CClassX. In a form in PROJECT.vbp:

Dim jOjbect As CClassX --doesn't work anymore but..

Dim jObject as PROJECTX.CClassX --works

I can't very well go around changing all my code. Where's the checkbox I have to uncheck? help!

Someone had shared 2 classes with this project in Visual Source Save and changed the instancing from some kind of "public" to "private". I changed the instancing back to "global multi use" on the classes and I can make intellisense of things again.
