It appears that Autodesk has not provided a way to remove projects from the Project Manager without deleting the projects. I want to be able to select a project (one at a time) in Project Manager and remove it from the list but not delete the project from the network server. If not, it should be possible. You cannot work forever and continually build up projects in the Project Manager. I can't believe you didn't provide a way to manage it in "Project Manager". It's more like a model and drawing manager than a project manager.
