Thanks for the bump, I hadn't seen this post before. I made some changes to support nested projects in Visual Studio solutions and I'm trying to replicate this. A few questions... how did you disable the project in Visual Studio? It auto-disables it if I rename the directory that the project's in, but is there a manual way to do it? When I load the solution in SlickEdit with the disabled project, SlickEdit creates a node for that project with no files underneath, and when I do a workspace-wide search, I get no "Failed to open:" errors. Can you tell me specifically how those VS projects became disabled?
