Visual Studio.Net Solution with two or more components

I have a Visual Studio.Net solution with two Visual Studio (VS) projects. Each VS project is in a single RTC component and the component are designed to be maintained separately. However, when the VS.Net solution is opened with both components/VS projects only one projects are loaded, and the other component unloads. I cannot get both components to be loaded at the same time. The repository workspace I am using, has both components, and the components are added at the appropriate baseline for the effort.

I can only work on the loaded component/VS project. When I want to work on the other component/ VS project, I need to load the component, and that causes the other component to unload. Again both components are in the same repository workspace.
