I have a control that is made up of a custom assembly and another custom web
control that I cannot declare and instantiate on another web pages
code-behind page.  Sometimes the IDE will recognize it as a class but then I
compile and an get build failure ie "did you forget to reference ..."  Any
help on this would be great.
